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.

Text Solution

Verified by Experts

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`
