0.30 g of a substance gives 0.88 g of carbon dioxide and 0.54 g of wat

1.	0.30 g of a substance gives 0.88 g of carbon dioxide and 0.54 g of water. Calculate the percentage of carbon and hydrogen in it
Answer» Solution :(i) Weight of organic compound = 0.30 G Weight of carbon-dioxide= 0.88 g Weight of water = 0.54 g Percentage of HYDROGEN : 18 g water contains 2 g of hydrogen `:."0.54" g"` of water contain `=2/(18)xx0.54g` of hydrogen `:.""%` of hydrogen `=2/(18)xx(0.54)/(0.30)xx100=(2)/(18)xx(54)/(0.3)` `""%` of H = `0.111xx180=19.888~~20%` Percentage of carbon : 44 g of `CO_(2)` contains 12 g of carbon 0.88 g of `CO_(2)` contains = `(12)/(44)xx0.88g` of carbon `:.""%` of carbon `=(12)/(44)xx(88)/(0.3)=(24)/(0.3)` `""%` of carbon `=80%` (ii)
