0.26 g of an organic compundgave 0.039 g of water and 0.245 g of CO_2

1.	0.26 g of an organic compundgave 0.039 g of water and 0.245 g of CO_2 on combustion. Calculate the percentage of carbon and hydrogen.
Answer» Solution :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 watercontains 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%`
