InterviewSolution

1.	0.2475 gm of an organic substance gave on combustion 0.495 gm of `CO_2` and `0.2025gm` of `H_2O`. Calculate the percentange of carbon and hydrogen in it.
Answer» 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`
