Number of moles of CaCO₃ = given mass / molar mass = 100/100 = 1
CaCO₃ ------------> CaO + CO₂
According to the above Equation, 1 mole of CaCO₃ on heating gives 1 mole of CaO (Calcium oxide).
So, Mass of 1 mole of CaO = 1 x 56 = 56 grams
Thus, 56 grams of Calcium oxide is obtained on heating 100 grams of Calcium carbonate.
Hope it helps!!

Answer:
CaCo3 give CaO and Co2 on heating.
Given that CaCo3=100g(molecular mass)
Therefore mass of CaO is 40×1+16×1=56(molecular mass)
