nC=(48/12)=4 nH=(8/1)=8 nD=(64/16)=4 In 60g;nC:nH:nO 2:4:2 CH3COOH

Q. $120$ grams of an organic compound contains $40% C$ by mass, $8 g$ -atom of $H$ and $64$ grams of oxygen, The molecular formula of compound is :

$C_{2} H_{5} O H$

$C H_{3} OC H_{3}$

$C H_{3} COO H$

$C H_{3} COC H_{3}$

$n_{C} = \frac{48}{12} = 4$
$n_{H} = \frac{8}{1} = 8$
$n_{D} = \frac{64}{16} = 4$
In $60 g; n_{C} : n_{H} : n_{O}$
$2 : 4 : 2$
$C H_{3} COO H$
