0.20 g of an organic compound forms 0.5764 g of `CO_(2)` and 0.1512 g of water on combustion. Calculate the percentage of carbon and hydrogen in the compound.

Explanation

Mass of the organic compound =0.20 g
Mass of `CO_(2)` formed = 0.5764 g
Mass of `H_(2)O` formed = 0.1512 g
Percentage of `C=12/44 xx("Mass of carbon dioxide formed")/("Mass of compound")xx100`
`=12/44xx((0.5764 g))/((0.20 g))xx100=78.6 %`
Percentage of `H=2/18xx("Mass of water formed")/("Mass of compound")xx100`
`=2/18xx((0.1512 g))/((0.20 g))xx100=8.4 %`
