Under certain conditions, the substance calcium carbonate can be broken down to form calcium oxide and carbon dioxide. If 31.7 g

klio [65]

Answer:

$13.93\ \text{g}$

Explanation:

Molecular weight of $CaCO_3$ = 100.0869 g/mol

Mass of $CaCO_3$ = 31.7 g

Moles of $CaCO_3$ = $\dfrac{31.7}{100.0869}=0.3167\ \text{mol}$

Moles of both $CaO$ and $CO_2$ is $0.3167\ \text{mol}$

Molecular weight of $CO_2$ = 44 g/mol

Mass of $CO_2$ = $44\times 0.3167=13.93\ \text{g}$

The mass of carbon dioxide formed simultaneously is $13.93\ \text{g}$ .
