0.2346 g of an organic compound containing C, H & 0, on combustion gives 0.2754 g of H_(2)0 and 0.4488 g CO_(2) . Calculate the % composition of C, H & 0 in the organic compound.

Answer»

Solution :WEIGHT of organic substance (W) = 0.2346 g
Weight of water (x) = 0.2754 g
Weight of `CO_(2)` (y) = 0.4488 g
`"Percentage of CARBON" = (12)/(44) xx (y)/(w) xx 100 = (12)/(44) xx (0.4488)/(0.2346) xx 100 = 52.17%`
`"Percentage of hydrogen" =(2)/(18) xx (x)/(w) xx 100=(2)/(18) xx (0.2754)/(0.2346) xx 100=13.04%`
Percentage of oxygen =[100-(52.17+13.04)]=100-65.21=34.79%
