Ammonia react with hydrogen bromide to produce ammonium bromide.
NH3 + HBr = NH4Br.
Let’s calculate the number of moles of hydrobromic acid.
n (HBr) = V / Vm = 15 L / 22.4 mol / L = 0.67 mol.
From the reaction equation it follows that the substances are taken in equal proportions, which means the volume of ammonia is equal.
V (NH3) = n • Vm = 0.67 mol • 22.4 mol / l = 15 liters.
