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

Here mass of the organic substance taken `=0.2475gm` mass of `CO_2` formed `=0.4950gm`, mass of `H_2O` formed `=0.2025gm`.
(i) percentage of carbon in the compound
`=(12)/(44)xx0.4950xx(100)/(0.2475)=54.54`
(ii). Percentage hydrogen in the compound
`=(2)/(18)xx0.2025xx(100)/(0.2475)=9.09`
