Question

How much limestone is needed to obtain 56 g of quicklime? Atomic mass are:
Ca= 40 u, C= 12 u, O= 16 u​

Answer 1

Answer:

The molar mass of limestone is 100 g (= mass of Ca + mass of C + 3 x mass of O = 40 + 12 + 3 x 16). Similarly, the molar mass of lime is 56 g. Thus, we can also say that 100 g of limestone produces 56 g of lime. Or, 1 g of lime is produced by 100/56 g limestone
