Answer the case-based question given below:
 
When calcium carbonate (limestone) is heated, it decomposes to form calcium oxide (quicklime) and carbon dioxide gas. If 100 g of calcium carbonate is heated and 44 g of carbon dioxide gas is released, find the mass of calcium oxide formed.
 
Mass of reactant =
Mass of \(CO_2\) liberated =
According to law of conservation of mass,
Mass of calcium oxide =
