This is a mass stoichiometry problem. Start with the balanced equation:
CaCO3 --> CaO + CO2.
Do a conversion from 50g CaO to moles:
56g/1mol=50g/x, x=.9 moles.
The equation is balanced as written, with all coefficients understood to be 1.
So: .9 moles CaO means .9 moles CaCO3.
Do another conversion from moles to grams:
100g/1mol=x/.9 moles.
Solve for x to get 90 grams.
(56g=molar mass of calcium oxide; 100g=molar mass of calcium carbonate.)

How many moles are there in 200 grams of Calcium Carbonate?
For a partly ionically bonded compound such as calcium carbonate, the gram formula mass is substituted for a mole, which technically exists only for purely covalently bonded compounds. The gram formula mass for calcium carbonate is 100.09. Therefore, 200 grams constitutes 200/100.09 or 2.00 gram formula masses of calcium carbonate, to the justified number of significant digits.

How many grams of calcium in 418 grams of Ca CO 3?
Calcium has Wt 40, carbon is 12 and oxygen 16, so the MWt of calcium carbonate is 40+12+3x16=100. As this contains 40 calcium, calcium carbonate is 40% calcium. 40% of 418 is 167.2grams
