How much of a solution containing 0.05 mass fraction, or 5%, hydrogen chloride will be required to react with 11.2 g of potassium carbonate?
KHCO3 + HCl → KCl + CO2 + H2
The ratio of potassium bicarbonate and hydrogen chloride 1: 1
Molar mass of KHCO3 100 g / mol
n = 11.2 / 100 = 0.112 mol
m (HCl) = 0.112 * 36.5 = 4.09 g
m solution = 4.09 / 0.05 = 81.98 g
