Question

159 l of hydrogen gas reacts with excess chlorine gas. what is the maximum amount of gas product that can be formed at stp

Answer 1

At standard conditions, the standard volume for any gas is 22.4 L/mol. Therefore the amount of moles of hydrogen gas is:

Moles of H2: 159 L/22.4 L/mol = 7.1 mol

The reaction would be:

H₂ + Cl₂ --> 2 HCl

Moles of HCl produced: 7.1 mol H₂ * 2 mol HCl/1 mol H₂ = 14.2 mol HCl
