What mass of CO2 will be produced when 50 g of CaCO3 decomposes?

CaCO 3 decomposition: CaCO 3 -> CaO + CO 2 The first thing to do here is to calculate the relative formula mass of CaCO 3 and CO 2 . RFM of CaCO 3 = 40 g + 12 g + (16 g x 3) = 100 g RFM of CO 2 = 12 g + (...

The relative formula mass of CaO is 56 and the relative formula mass of CO2 is 44. What is the mass of CaO that can be obtained from 200 g of CaCO3. CaO3 -> CaO + CO2

We are given the relative formula mass (RFM) of CaO and CO 2 , we should therefore calculate the RFM of CaO 3 : RFM of CaCO 3 = 40 + 12 + (16 x 3) = 100 If we look at the reaction in the question, we can see...
