The molecular formula of dye:
A major textile dye manufacturer developed a new yellow dye with a molecular formula [tex]C_{15}N_{3}H_{15}[/tex].
Given:
Percentage composition:
C = 75.95%
N = 17.72%
H = 6.33%
Molar mass = 240 g
To find: molecular formula of dye
Calculation:
Let's assume the mass of the compound is 100 gm.
So, Mass of C = 75.95 gm
Mass of N = 17.72 gm
Mass of H = 6.33 gm
The number of moles = given mass/mass
Therefore, the number of moles of C = 75.95/12 = 6.33
The number of moles of N = 17.72/14 = 1.27
Number of moles of H =6.33/1 = 6.33
Simplest ratio:
C = 6.33/1.27 = 4.98 =5
N = 1.27/1.27 = 1
H = 6.33/1.27 = 4.98 =5
Therefore, the empirical formula is [tex]C_{5}NH_{5}[/tex]
The mass of empirical formula = 12 x 5 + 14 + 1 x 5 = 79 gm
Number of moles= molar mass/ empirical formula
n = 240/79 = 3.04 =3
Therefore, molecular formula = empirical formula x n
Hence, molecular formula = [tex]C_{15}N_{3}H_{15}[/tex]

2 C4H10 13 O₂ = 8 CO2 +10 H₂O
Answer:
1.) 13 g C₄H₁₀
2.) 41 g CO₂
Explanation:
To find the mass of propane (C₄H₁₀) and carbon dioxide (CO₂), you need to (1) convert mass O₂ to moles O₂ (via molar mass), then (2) convert moles O₂ to moles C₄H₁₀/CO₂ (via mole-to-mole ratio from equation coefficients), and then (3) convert moles C₄H₁₀/CO₂ to mass C₄H₁₀/CO₂ (via molar mass). It is important to arrange the ratios in a way that allows for the cancellation of units. The final answers should have 2 sig figs to match the sig figs of the given value.
Molar Mass (C₄H₁₀): 4(12.011 g/mol) + 10(1.008 g/mol)
Molar Mass (C₄H₁₀): 58.124 g/mol
Molar Mass (CO₂): 12.011 g/mol + 2(15.998 g/mol)
Molar Mass (CO₂): 44.007 g/mol
Molar Mass (O₂): 2(15.998 g/mol)
Molar Mass (O₂): 31.996 g/mol

Mass after 60 years:
2 kg of cesium-137 will remain after 60.0 years.
What is Half-life?
The duration needed for a quantity to decrease to half of its initial value is known as the half-life.
Given:
N0 = is the initial amount of cesium-137 = 8.0 Kg
N = is the amount remaining after a time = Unknown
t = Duration of cesium-137 decay in 8.0 Kg = 60 years
t1/2 = half-life of cesium-137 = 30.0 years

The difference between the calculated voltage (based on standard potentials) and the actual voltage required to cause electrolysis is called overvoltage.
ElectrolysisElectrolysis is the technique of causing a chemical change in a substance by passing an electric current through it. The substance either loses or gets an electron during the chemical transition (oxidation or reduction). The procedure is carried out in an electrolytic cell, a device made up of positive and negative electrodes that are kept apart and submerged in a solution with ions that are both positively and negatively charged. The chemical that needs to be converted might either be dissolved in the solution or could form the electrode. The negatively charged electrode (cathode) receives electrical current (i.e., electrons), which travels there and combines with the components of the solution to convert them (reduced).
