Question

The percentage of nitrogen and hydrogen in a compound are 82.4 and 17.6 find out the molecular formula ratio of this compound?

Answer 1

Answer:

We can find the lowest whole-number ratio of the elements in the compound: the lowest whole number ratio= (molar amount)/(lowest molar amount) N/H = 5.89/17.6 (divide each of the found values by 5.89), N/H = 1/2.99 ≈ 1/3. The empirical formula of the compound is N1H3 or NH3.
