CaCO3 = CaO+CO2. what weight of CaO will be produced by heating: a) 100 kg pure CaCO3 b) 100 g limestone with 95 % purity? Share with your friends Share 0 Vartika Jain answered this Dear Student, CaCO3 → CaO + CO2 100 g 44 g(a) Now, 1 mol i.e. 100 g of CaCO3 gives 1 mol i.e. 44 g of CO2So, 100 kg i.e. 100000 g of CaCO3 will give 44100×100000=44000 g or 44 kg of CO2(b) 95% purity means 95 g of CaCO3 is present in 100 g of sample. 1 mol i.e. 100 g of CaCO3 gives 1 mol i.e. 44 g of CO2So, 95 g of CaCO3 will give 44100×95=41.8 g of CO2 0 View Full Answer
