0.2475g of an organic compound gave on combustion 0.4950g of `CO_(2)` and 0.2025g of `H_(2)O` calculate the % of C `&` H in it.

Text Solution

Verified by Experts

Wt. of organic compound (w) = 0.2475 g
Wt. of `CO_(2)` (b) = 0.4950 g
Wt. of `H_(2)O`(a) = 0.2025 g
`% of C= (12/44 xxb)/w xx100`
`= 54.54`
% of `H = (2/18 xxa)/w xx100`
`=(2/18 xx 0.2025)/0.2475 xx100 =9.09`
