On complete combustion, 0.246 g of an organic compound gave 0.198g of carbon dioxide and 0.1014g of water. Determine the percentage composition of carbon and hydrogen in the compound

Explanation

Percentage of `C=("At. Mass of C")/("Molar mass of" CO_(2))xx("Amount of" CO_(2))/("Wt. of organic compound")xx100`
`=(12)/(44)xx(0.198)/(0.246)xx100=21.95%`
Percentage of `H=("At. Mass of H X"xx2)/("Molar mass of" H_(2)O)xx("Amount of" H_(2)O)/("Wt. of organic compound")xx100`
`=(2)/(18)xx(0.1014)/(0.246)xx100=4.58%`
