An organic compound contains carbon, hydrogen, oxygen and nitrogen in the weight ratio `3:1:8:3.5`. Calculate its empirical formula.

Explanation

Ratio of atoms, C : H : O : N = `(3)/(12) : (1)/(1) : (8)/(16) : (3.5)/(14) = 0.25 : 1 : 0.5 : 0.25 = 1 : 4 : 2 : 1`
The empirical formula is `CH_(4)O_(2)N`
