1. What is the volume of 4.62 g of mercury? The density of mercury is 13.5 g/cm?​

Answers

Answer 1

Answer:

The answer is

0.34 cm³

Explanation:

The denisty of a substance can be found by using the formula

[tex]Density(\rho) = \frac{mass}{volume} [/tex]

Making volume the subject we have

[tex]volume = \frac{mass}{Density} [/tex]

From the question

mass = 4.62 g

Density = 13.5 g/cm³

Substitute the values into the above formula and solve for the volume

That's

[tex]volume = \frac{4.62}{13.5} [/tex]

= 0.34222……

We have the final answer as

0.34 cm³

Hope this helps you

Which of the following is correct?

a. One molecule of methane reacts with two molecules of oxygen to produce one molecule of carbon dioxide and two molecules of water.
b. One gram of methane reacts with two grams of oxygen to produce one gram of carbon dioxide and two grams of water.
c. One mole of methane reacts with two moles of oxygen to produce one mole of carbon dioxide and 2 moles of water.
d. a and c are correct.

Answers

Answer:

The correct option is d. a and c are correct.

Explanation:

First, we will write a balanced equation for the reaction between methane (CH₄) and oxygen (O₂).

The reaction between methane (CH₄) and oxygen (O₂) gives carbon dioxide (CO₂) and water (H₂O). The balanced equation for the reaction is shown below

CH₄ + 2O₂ → CO₂ + 2H₂O

The number beside each molecule on the reactant side indicates the number of the individual molecules required for complete reaction and also the number beside each molecule on the product side indicates the number of the individual molecules produces in the reaction.

This means,

One molecule of methane will react with two molecules of oxygen to produce one molecule of carbon dioxide and two molecules of water. Hence, option a is correct.

From,

Number of molecules = Number of moles × Avogadro's number

Since Avogadro's number is constant, hence, the equation also means,

One mole of methane will react with two moles of oxygen to produce one mole of carbon dioxide and two moles of water. Hence, option c is correct.

For the mass relationship,

Mass = Number of moles × Molar mass

Molar mass of methane = 12 + 1(4) = 16 g/mol;

∴1g of methane = 0.0625 mole

Molar mass of oxygen = 16 g/mol;

∴2g of oxygen = 0.125 mole

Molar mass of carbon dioxide = 12 + 16(2) = 44 g/mol;

∴1g of CO₂ = 0.02272 mole

Molar mass of water = 1(2) + 16 = 18 g/mol;

∴2g of water = 0.11111 mole

From the equation 0.0625 mole of methane reacts with 0.125 mole of oxygen to produce 0.0625 mole of carbon dioxide and 0.125 moles of water.

Hence, option b is not correct.

SOLVE Use the density formula to solve the following problems. A sample of a substance has a volume of 60.5 mL and a density of 1.20 g/mL. What is the mass of the sample?

Answers

Density = Mass/Volume
Therefore, Mass = Density x Volume

So the mass of the sample is 1.20 g/mL x 60.5 mL = 72.6 g

The mass of the sample is 72.6 g. when a sample has a volume of 60.5 mL and a density of 1.20 g/mL.

What is the density?

Density may be defined as the physical property of any object. It may be characterized as the measurement of quantity or mass per unit of volume in a particular substance.

According to the question, the volume of a sample = 60.5 mL.

The density of a sample = 1.20 g/mL.

Now, the formula for density is as follows:

Density = Mass/Volume.

But we have to calculate the mass of the sample, so the modified formula is = Mass = Density x Volume.

∴ Mass = 1.20 g/mL x 60.5 mL =  72.6 g.

Therefore, the mass of the sample is 72.6 g. when a sample has a volume of 60.5 mL and a density of 1.20 g/mL.

Answers

Answer:

+1

Explanation:

Sodium has one electron in its outermost shell. Sodium can not be able to accept seven electrons because the energy required for that process is very high. Sodium would rather loose its only valence electron to form a univalent positive ion Na^+.

This is an easier process. When sodium looses one electron, it now has a charge of +1.

How many cubic centimeters of an ore containing only 0.22% gold (by mass) must be processed to obtain $100.00 worth of gold? The density of the ore is 8.0 g/cm3 and the price of gold is $818 per troy ounce. (14.6 troy oz = 1.0 ordinary pound, called an avoirdupois pound; 1 lb = 454 g)

Answers

Answer:

The cubic centimetres of the ore containing 0.22% gold (by mass) that must be processed to obtain the $100.00 worth of gold is approximately 216 cm³

Explanation:

The percentage by mass of gold in the ore = 0.22%

The density of the ore = 8.0 g/cm³

The price of the gold = $818 per troy ounce

14.6 troy oz = 1.0 pound

1 lb = 454 g

Given that one troy ounce = $818

$100 worth of gold = 1/818 ×100 troy ounce = 100/818 troy ounce

1 troy oz = 1.0/14.6 lb

100/818 troy oz =  100/818 × 1.0/14.6 lb = 250/29857 lb ≈ 0.0084 lb

1 lb = 454 g

250/29857 lb = 454 × 250/29857 g ≈ 3.8015 g

$100 = 3.8015 g worth of gold

The mass, M, of the ore containing 3.8015 g of gold is given as follows;

0.22% of M = 3.8015 g

0.22/100 × M = 3.8015 g

M = 3.8015 g × 100/0.22 = 1727.933 g

The volume, V, of the ore containing 3.8015 g of gold is given as follows;

Density of ore = Mass of ore/(Volume of ore)

Volume of ore = Mass of ore /(Density of ore)

The density of the ore = 8.0 g/cm³

Volume of ore = 1727.933 g /(8.0 g/cm³) = 215.99 cm³ ≈ 216 cm³

Therefore, the cubic centimetres of the ore containing 0.22% gold (by mass) that must be processed to obtain the $100.00 worth of gold ≈ 216 cm³.

His most important discovery was the fact that heating wine to 55°C will lead to the death of microorganisms and prevented wine from spoiling and did not affect its taste. This process is known as pasteurization.

A chemist encounters an unknown metal. They drop the metal into a graduated cylinder containing water, and find the volume change is 6.9 mL. If the metal weighs 4.9 g, what is the density of the metal?

Answers

Answer:

The density of the metal is 0.561 g/mL

Explanation:

The computation of the density of the metal is shown below;

As we know that

The Density of the metal is

[tex]= \frac{mass}{volume}[/tex]

where,

Mass = 4.9g

Change in volume = 6.9 mL

Now place these values to the above formula

So, the density of the metal is

[tex]= \frac{4.9g}{6.9mL}[/tex]

= 0.561 g/mL

Hence, the density of the metal is 0.561 g/mL

We simply applied the above formula so that the correct density could arrive
