A compared of magnesium nitric contains 72% of magnesium and 28% of nitrogen. what is the empirical formula of magnesium nitric. and the answer is Mg 3 N 2

how to do the solution.

The empirical formula is the smallest comparison of atoms of compound =mole ratio of the components

The principle of determining empirical formula

•Determine the mass ratio of the constituent elements of the compound.  

•Determine the mole ratio by dividing the percentage by the atomic mass

The empirical formula :

mol ratio Mg : N ⇒

answer: h+ its less than oh
