1.	In Leibig's method 0.24 g of organic compound on combustion with dry oxygen produced of 0.62 g of CO_(2) and 0.11 g of H_(2)O. Determine the percentage composition of the compound.
Answer» SOLUTION :Mass of organic COMPOUND `=m=0.24g` Mass of carbon dioxide formed `=0.62 g` Mass of water formed `=0.11 g` Percentage of carbon `=12/4xx0.62/0.24xx100=70.45` Percentage of hydrogen `=2/4xx0.11/0.24xx100=5.09` Percentage of oxygen `=[100-(70.5+5.0)]=24.46`
