Question

Calculate the mass of $C O_{2}$ produced by heating $20 g$ of pure limestone $(C a C O_{3})$ .

Open in App

Solution

Given mass of pure $C a C O_{3} = 20 g$
$100 g$ of $C a C O_{3}$ produce $44 g$ of $C O_{2}$
So, $20 g$ of $C a C O_{3}$ will produce $(\frac{44}{100} \times 20) = 8.8 g$ of $C O_{2}$
