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
