What is the volume of carbon dioxide formed when interacting with hydrochloric acid 100 g

What is the volume of carbon dioxide formed when interacting with hydrochloric acid 100 g of potassium carbonate containing 10% impurities

2HCl + K2CO3 = 2KCl + H2O + CO2.
Salt amount:
m = 100 g * (100% – 10%) / 100% = 90 g.
N = 90/138 = 0.652, the same amount of CO2 will be released, which means that its volume is: 0.652 * 22.4 = 14.6 liters.
