0.26 g of an organic compund gave 0.039 g of water and 0.245 g of `CO_2` on combustion. Calculate the percentage of carbon and hydrogen.

Explanation

Weight of organic compound =0.26 g
Weight of water =0.039 g
Weight of `CO_2`= 0.245 g
Percentage of hydrogen
18 g of water contains 2 g of hydrogen
0.039 mg of water contains`-(2)/(18)xx(0039)/(0.26)`of H
% of hydrogen `-(0.39)/(0.26)xx(2)/(18)xx100=1.66%`
Percentage of csarbon
44 g of `CO_2` contains 12 g of C
0.245 g `CO_2` contains=`(12)/(44)xx(0.245)/(0.26)g` of C
%of carbon =`(12)/(44)xx(0.245)/(0.26)xx100=25.69%`
