Answer:
You need the atomic mass of calcium, oxygen and carbo; the balanced chemical equation and the molar ratio between Calcium carbonate and calcium oxide.
Explanation:
1.- If you know the atomic mass of the elements, you can calculate the molar mass of Calcium Carbonate (CaCO3) and the mass of Calcium Oxide (CaO).
2.- The balanced equation is CaCO3 -> CaO + CO2
3.- The molar ratio between CaCO3 and CaO is 1:1, which means that the descomposing of one mole of calcium carbonate produce one mole of calcium oxide.
4.- The last thing you should do is to conver the 4.7 kg of CaCO3 to moles and with the molar ratio calculate the mass of CaO
