Calculate the weight of lime (CaO) obtained by heating 200 kg of 95% pure lime stone (CaCO₃).
114.9 kg
155.6 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.
190 kg CaCO3 gives CaO = = 106.4 kg
