0.4g of a compound on complete combustion gave 56ml of `CO_(2)` at 760mm and `0^(@)C`. The percentage of carbon in the compound is

A

50

B

60

C

27.5

D

7.5

Text Solution

Verified by Experts

The correct Answer is:
D
`W_(CO_(2))=(56)/(22400)xx44`
`%C=(W_(CO_(2)))/(0.4)xx(12)/(44)=(1)/(400xx0.4)xx12=7.5%`
