Ratio of atoms C: H: N: O :: (20.0/12): (6.66/1): (47.33/14): (26.01/16) =1.67: 6.66: 3.38: 1.63 =1: 4: 2: 1 Empirical formula = CH 4 N 2 O Molar empirical formula mass =60 g Molecular formula = CH 4 N 2 O Thus x=2

Q. An organic compound contains $20.0% C$ , $6.66% H$ , $47.33% N$ and the rest was oxygen. Its molar mass is $60 g m o l^{- 1} .$ The molecular formula of the compound is $C H_{4}$ $N_{x} O,$ the value of $x$ is ______

Ratio of atoms

$C : H : N : O :: \frac{20.0}{12} : \frac{6.66}{1} : \frac{47.33}{14} : \frac{26.01}{16}$

$= 1.67 : 6.66 : 3.38 : 1.63$

$= 1 : 4 : 2 : 1$

Empirical formula $= C H_{4} N_{2} O$

Molar empirical formula mass $= 60 g$

Molecular formula $= C H_{4} N_{2} O$

Thus $x = 2$
