if the concentration of the stock (provided) cu(nh3)42 was 0.068 m, what concentration will the cu2 be in beaker
The concentration of the cu2+ in the braker will be 0.068 molar.
Concentration is known as the measure of the relative proportions of two or more quantities in a mixture of solution. Concentration determines the number of molecules are present in the solution. Concentration also determines the acidity and basicity of the solution.
In the given condition we have 0.068 molar of copper in the solution.
Therefore,
[Cu2+] = 1 molCu(NH3)/ l x 1 mol Cu2+/ 1 moleCu(NH3)
1 molCu(NH3) gets cancelled on both the sides.
as we know, from the given condition [Cu2+] = 0.068 molar
Therefore, 0.068 = 1 mol Cu2+ / l
Therefore, the concentration in the beaker of the copper will be 0.068molar.

calculate the empirical formula for a compound that contains 40.0% carbon, 6.70% hydrogen, and 53.3% oxygen
The empirical formula for the hydrocarbon is CH₂O.
First, we assume that we have 100g of formaldehyde
According to the question we have 40.0% of carbon, 6.70% of hydrogen, and 53.3% of oxygen. With help of this, we calculate the moles of individual elements.
Moles of C = 40.0 g of C × 1 mol of C / 12.01 g C = 3.331 mol C
Moles of H = 6.7 g of H × 1 mol of H / 1.008 g H = 6.65 mol H
Moles of O = 53.3 g of O × 1 mol of O / 16.00 g O = 3.331 mol O
To get the molar ratio we divide all the moles by the smallest moles which are 3.331. From here the ratio comes out to be C: H: O = 1:2:1.
Thus the empirical formula is, CH₂O.

Stirring a solute into a solution increases the net dissolving rate because stirring affects how quickly a solute dissolves in a solvent but does not affect how much solute will dissolve.
The sum of solute that will break up is influenced by temperature - more will break down at higher temperatures. Typically called the solubility of the solute.
Charts of the solvency at distinctive temperatures can be utilized to decide how much will break down, or at which temperature a given arrangement will be gotten to be saturated.
Stirring moves the dissolvable particles around, permitting them to connect with the strong pieces of undissolved solute and transporting the broken-up solute absent into the bulk of the solution.
In the nonappearance of blending, the concentration of solute will be most noteworthy near the pieces of solute, so more solute won't break down into the arrangement until the broken-up solute has been transported absent by dissemination.

Copper(i) iodide added to table salt as a dietary source of iodine. 0.238mm of CuI are contained in 1.00 lb (454 g) of table salt containing 0.0100% CuI.
What is molar mass?Mass per mole is a definition of molar mass. Molar mass is the total mass of all atoms in substance that makes up a mole. It is measured in gram-per-mole units.
In the case of single elements or individual atoms, the molar mass is just the element's mass given in atomic mass units. Atom's atomic mass and molar mass are exactly equal.
Given,
Mass of table salt is 1.00 lb = 454 g
Copper(I) Iodine (CuI) present in the table is 0.0100% by mass or
CuI present in the 1 pound of salt = 0.01% of 454 g = 0.0454 grams
Now,
Molar mass of CuI = 63.54 grams + 126.90 grams
Molar mass of CuI = 190.44 grams
∴ number of moles of CuI present in 1 pound salt = Mass / Molar mass
Moles of CuI= 0.0454 / 190.44
Moles of CuI = 2.38 × 10⁻⁴ moles
Moles of CuI = 0.238 millimoles

What is Boyle's Law?Boyle's Law, a cornerstone of chemistry, describes the behavior of a gas sustained at a constant temperature. Robert A. Boyle discovered this law in 1662: at a certain temperature, the volume of a gas is inversely proportional to the pressure it exerts. To put it another way, if a gas is driven into a closed place, it will condense to fit the area but raise the pressure on the container.
Boyle's law, which is arguably a clearer way to put it, is the relationship between pressure and volume. Mathematically, Boyle's law can be written as pV=k, where p stands for the pressure, volume, and mass of the gas and k is a constant.
The solution is straightforward when temperature and moles are constant,

Newton's laws of motion are 3 fundamental laws of classical mechanics that describe the connection between the motion of an object and the forces acting on it. those legal guidelines may be paraphrased as follows: A body stays at relaxation, or in movement at a steady speed in a straight line, unless acted upon through pressure.
Within the first regulation, an object will not alternate its motion unless pressure acts on it. inside the 2nd law, the force on an item is equal to its mass times its acceleration. inside the third law, when two objects interact, they practice forces on each other of identical value and opposite routes. Newton's 2nd regulation is one of the most important in all of physics. For a frame whose mass m is regular, it is able to be written inside the shape F = ma, in which F (pressure) and an (acceleration) are both vector quantities. If a body has a net force acting on it, its miles are multiplied in accordance with the equation.

what happens to the solubility of mg(oh)2 in water if 0.1 m hno3 is added to the solution at 298 k? (ksp
We interrogate the equilibrium,
S=2.32×10−4⋅mol⋅L−1
what is solubility?
Solubility in chemistry refers to the capacity of one material, the solute, to create a solution with another substance, the solvent. Insolubility is the solute's inability to create such a solution.
The extent of a substance's solubility in a certain solvent is commonly assessed as the concentration of the solute in a saturated solution, one in which no more solute can be dissolved.
At this stage, the two compounds are considered to be in solubility equilibrium. Some solutes and solvents may have no such limit, in which case the two substances are said to be "miscible in any amounts."
We interrogate the equilibrium
Mg(OH)2⇌Mg+2 +2HO−
And Ksp=[Mg2+][−OH]2
And now if we call the solubility of Mg(OH)2 S, then by definition, S=[Mg2+], and 2S=−OH.
And thus Ksp=S×(2S)2=4S3
And so (finally!), S=3√Ksp4
S=3√5.0×10−114=2.32×10−4⋅mol⋅L−1

O D. The solution is basic.
The correct answer is A. A pH of 7 say about a solution is The solution is neutral.
What is a pH of 7A pH of 7 indicates a neutral solution. The pH scale is a logarithmic scale that measures the acidity or alkalinity (basicity) of a solution. A pH value of 7 is considered neutral, which means the concentration of hydrogen ions (H+) is equal to the concentration of hydroxide ions (OH-) in the solution. In other words, the solution is neither acidic nor basic.
Acidic solutions have a higher concentration of hydrogen ions (H+), which makes them more acidic. The lower the pH value, the higher the concentration of H+ ions and the stronger the acid.

What is the volume of a nugget of gold that has a mass of 93,300g?
Answer:

Explanation:
Gold has density of 19.30 g/ml
so according to d = m/V
V = m/d = 93,300/19.30 = 4834.19689119 = 4834.20 ml or 4.8342 L
The volume of nuggets of gold that has a mass of 93,300g is 4834.20 ml or 4.8342 L.
What is volume?Volume is the space occupied by a three-dimensional object.
Density is the mass per unit volume. Density is a scalar quantity. It is denoted by d and the symbol for density is given as rho, a Greek symbol. Density is calculated as mass divided by volume.
Density is directly proportional to mass and inversely proportional to volume. Thus, with an increase in density, mass increases and volume decreases, and vice-versa
Gold has a density of 19.30 g/ml
so according to density = mass/ volume
V = m/d = 93,300 / 19.30 = 4834.19
4834.20 ml or 4.8342 L

The average atomic mass of iron Isotopes is 55.90 amu.
What is the average atomic mass?We know that because there is a phenomenon that we call isotopy, the average atomic mass of the elements is often not a whole number. The atoms of the elements tend to differ in the number of the neutrons that they posses. Thus isotopes are the atoms of the same elements that do not have the same number of neutrons.

what is the percent by mass (m/m%) of ethanol (c2h6o) solution that was prepared by dissolving 50.500 g of ethanol into water to a final volume of 750.0 ml? assume the solution has a density of 1.20 g/ml.
The (m/m%) concentration of ethanol is the solution is 5.55%.
The density of the solution is given to be 1.20 g/ml. The volume of the solution is 750 ml.
We know,
Density = mass/volume
Mass of solution = Density of solution x Volume of solution
Mass of solution = 1.2 x 750
Mass of solution = 900 grams.
The mass of solute, ethanol is 50 grams.
So, (m/m%) of ethanol is,
(m/m%) of ethanol = Mass of ethanol/mass of solution x 100
(m/m%) of ethanol = 50/900 x 100
(m/m%) of ethanol = 5.55%.
So, the (m/m%) of ethanol is 5.55%.
