Expert Answer:

The reaction of CaCO3 with dil HCl can be represented as follows:
 
CaCO3 + 2HCl → CaCl2 + CO2 + H2O
 
From the reaction, 1 mole of calcium carbonate is required to react with 2 moles of hydrochloric acid to produce 1 mole of carbon dioxide.
Molar mass of:
CaCO3 = 100.09 g
HCl = 36.5 g
CO2 = 44.01 g
Hence, 100.09 g of calcium carbonate is required to produce 44.01 g of CO2.
