0.53 g of an organic compound 
when heated with excess of nitric acid (concentrated) and then with silver nitrate gave 0.75 g of silver bromide precipitate. 1.0 g of 
gave 1.32 g of 
gas on combustion. The percentage of hydrogen in the compound (x) is 
%. [Nearest Integer]
[Given: Molar mass in 
Compound 
]

From AgBr precipitate:
equals 0.00399 mol Br, so the compound has one Br atom.
From combustion of 1.0 g:
equals 0.03 mol C.
The molar mass is found from 0.53 g sample:
.
From 1.0 g sample producing 
We have 
, giving 
.
Thus the molecular formula is 
with 
.
Percentage of hydrogen 
, which rounds to 
.
