Calculate the weight of lime (CaO) obtained by heating 200 kg of 95% pure lime stone (CaCO3).
104.4 kg
105.4 kg
212.8 kg
106.4 kg
100 kg impure sample has pure CaCO3 = 95 kg
200 kg impure sample has pure CaCO3 = 190 kg.
CaCO3 →CaO + CO2
100 kg CaCO3 gives CaO = 56 kg.
90 kg CaCO3 gives CaO = = 106.4 kg
