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

0.1304

B

0.5217

C

0.6521

D

0.113

Text Solution

Verified by Experts

The correct Answer is:
A
Increase in mass of U-tube =1.08g mass of water formed=1.08g
18g `H_(2)O-=2` g H
`1.08" g "H_(2)O=(2)/(18)xx1.08`
% of hydrogen=`(2)/(18)xx(1.08)/(0.92)xx100=13.04%`
