Calculate the volume of carbon dioxide at NTP evolved by strong heating of 20g calcium carbonate.

Text Solution

Verified by Experts

The balanced equation is
`underset(100g)underset(1"mol")(CaCO_(3)) to CaO+underset(=22.4 "litre at NTP")underset(1"mol")(CO_(2))`
100g of `CaCO_(3)` evolve carbon dioxide=22.4litre
20g `CaCO_(3)` will evolve carbon dioxide `=(22.4)/(100)xx20=4.48"litre"`
