What volume of gaseous hydrogen chloride HCl is formed in the reaction of chlorine Cl₂

What volume of gaseous hydrogen chloride HCl is formed in the reaction of chlorine Cl₂ with a mass of 71 g and hydrogen H₂ with a mass of 2 g?

H2 + Cl2 = 2 HCl

Let’s find the amount of reactants:

n (H2) = m (H2) / M (H2) = 2/2 = 1 mol;

n (Cl2) = 71/71 = 1 mol;

Substances are taken in stoichiometric proportions.

n (HCl) = 2n (H2) = 2 mol;

V (HCl) = n (HCl) × VM = 2 × 22.4 = 44.8 liters.

Answer: V (HCl) = 44.8 liters.
