On complete combustion, 0.246g 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

`{:(%C= (12)/(44) xx (m_(2) xx 100)/(m)),(=(12)/(44) xx (0.198 xx 100)/(0.246)),(=21.95%):}|{: ("where, m = mass of comp" =0.246gm ),(m_(2) = "mass of "CO_(2)),(=0.198 gm):}`
`{:(%H= (2)/(18) xx (m_(1) xx 100)/(m)),(=(2)/(18) xx (0.1010 xx 100)/(0.246)),(=4.58%):}|{:(m_(1) = "mass of " H_(2)O= 0.1010gm),("m = mass of comp"),(= 0.246):}`
