What is the volume of `CO_2` liberated (in litres) at 1 atmosphere and `0^@C` when 10 g of 100% pure calcium carbonate is treated with excess dilute sulphuric acid ? (Atomic mass Ca = 40, C = 12, O = 16)

A

0.224

B

2.24

C

22.4

D

224

Text Solution

Verified by Experts

The correct Answer is:
B
`underset("1mol (100 g) ")(CaCO_3) + H_2SO_4 to CaSO_4 + H_2O + underset("1mol (22.4L) )(CO_2)`
100 g of `CaCO_3` liberate `CO_2 = 22.4 L`
10 g of `CaCO_3` will liberate `CO_2 = (22.4)/(100) xx 10 = 2.24 L `
