0.92 g of an organic compound was analysed by combustion method. The mass of the U-tube increased by 1.08 g. what is the percentage of hydrogen in the compound?

A

`C=52.17%,H=13.04%,O=34.79%`

B

`C=50%,H=50%`

C

`C=32.19%,H=18.01%,O=49.8%`

D

`C=72%,H=28%`

Text Solution

Verified by Experts

The correct Answer is:
A
Mass of `H_(2)O=0.54g`
Mass of `CO_(2)=0.88g`
% of `C=(12)/(44)xx(0.88)/(0.46)xx100=52.17%`
% of `H=(2)/(18)xx(0.54)/(0.46)xx100=13.04%`
% of `O=100-(52.17+13.04)=34.79`%
