Volume of `CO_(2)` obtained by the complete decomposition of 9.85 gm. `BaCO_(3)` is :

A

1.12 L

B

0.84 L

C

2.24 L

D

4. 96 L

Text Solution

Verified by Experts

The correct Answer is:
A
On decomposition , `BaCO_(3)` liberates `CO_(2)` as
`underset(197g)(BaCO_(3))toBaO+underset( "22. L at STP ")(CO_(2)uarr)`
`:'` 197 g of `BaCO_(3)`g gives =22. 4 L of `CO_(2)` at STP
`:.` 9.85 g of `BaCO_(3)` will give `=(22.4xx9.85)/(197)=1.12 L`
