A possible molecular formula : NH₄NO₂

Further explanation

Given

43.6% N 6.2% H 50.0% O.

Required

The molecular formula

Solution

A molecular formula is a formula that shows the number of atomic elements that make up a compound.

The empirical formula is the smallest comparison of atoms of compound forming elements.

(empirical formula) n = molecular formula

mol ratio for N : H : O

= 43.6/14 : 6.2/1 : 50/16

= 3.11 : 6.2 : 3.125 divide by 3.11

= 1 : 2 : 1

Empirical formula : NH₂O

Molecular formula : ( NH₂O)₂=N₂H₄O₂ or NH₄NO₂
