Expert Solution

ANSWER:

The given reaction is:

CaCO₃ CaO + CO₂

(a) Given,

mass of calcium carbonate = 300g

molecular mass of calcium carbonate = 100.0869 g/mol

number of moles of calcium carbonate = (given mass)/(molecular mass)

= (300 g)/(100.0869 g/mol)

= 2.9974 mol

From reaction,

1 mole of calcium carbonate generates = 1 mole of carbon dioxide

2.9974 mol of calcium carbonate generates = 2.9974 mole of carbon dioxide

Hence, 2.9974 moles of carbon dioxide can be generated from 300g of calcium carbonate.

(b) Given,

Number of moles of carbon dioxide = 2.9974 moles

molecular mass of carbon dioxide = 44.01 g/mol

mass of carbon dioxide = Number of moles x molecular mass

= 2.9974 mol x 44.01 g/mol

= 131.92 g

Hence, 131.92 grams of carbon dioxide can be generated from 300g of calcium carbonate.
