Let CaCO3(s) be consumed completely.
∴100g of CaCO3 gives =44g of CO2 gas
∴20g of CaCO, will give =

44

100

×20g of CO2
=8.8g of CO2
Now, HCl, be completely consumed.
73g of HCl give =44g of CO2 gas
∴20g of HCl gives =

44

73

×20g of CO2=12.05g of CO2
Hence, CaCO3 give least amount of CO2 gas. So, CaCO3 is limiting reactant
∴ Amount of CO2, formed will be 8.8g.
