Question

Every molecule of ammonia always has formula
NH3 irrespective of method of preparation or
sources. i.e. 1 mole of ammonia always contains
1 mol of N and 3 mole of H. In other words 17 gm
of NH3 always contains 14 gm of N and 3 gm of H.
Now find out % of each element in the compound.​

Answer 1

Answer:

Mass % of N in NH3

= (Mass of N in 1 mol NH3)/(Mass of 1 mol of NH3) × 100

= 14gm/17 × 100 = 82.35 %

Mass % of H in NH3

= (Mass of H in 1 mol NH3)/(Mass of 1 mol of NH3) × 100

= 3/17 × 100 = 17.65 %
