A

10 g

B

50 g

C

5 g

D

15 g

Text Solution

Verified by Experts

The correct Answer is:
C
`underset(100)underset(40+12+48)(CaCO_(3))overset("Heat")toCaO+underset(=44)underset(12+32)(CO_(2))`
`therefore 44 g CO_(2)` is obtained from `100g CaCO_(3)`
`therefore 2.2 g CO_(2)` is obtained from
`=(100 xx 2.2)/(44) = 5g`
