0.2475 g of an organic compound gave on combustion 0.4950 g of carbon

1.	0.2475 g of an organic compound gave on combustion 0.4950 g of carbon dioxide and 0.2025 g of water. Calculate the percentage of carbon and hydrogen in it.
Answer» Solution :WT. of organic COMPOUND `= 0.2475` g Wt. of `CO_2` produced `= 0.4950` g Wt. Of `H_2 O` produced `= 0.20 25` g Percentage of carbon `= (12)/(44) xx ("Wt. Of" CO_2)/("Wt. OFCOMPOUND") xx 100` `= (12)/(44) xx (0.34950)/(0.2475) xx 100 = 54.54` Percentage of hydrogen `= (2)/(18) xx ("Wt. of" H_2 O )/("Wt. of compound") xx 100` `= (2)/(18) xx (0.2025)/(0.2475) xx 100 = 9.09`
