Calculate the percentage of nitrogen in NH3 (Atomic Mass Of N =14 An H=1 Amu).


Open in App
Solution

Step 1:- Molecular mass of NH3

Given the atomic mass of N is 14 amu and that of H is 1 amu

Thus the molecular mass of NH3 = 14amu+3×1amu=17amu

Step 2:- Percentage composition of N

Percentage composition of N

= atomicmassofN×totalnumerofNpresentinthemolecule×100%totalmolecularmassofNH3

= 14amu×100%17amu

= 82.35%

Thus the percentage composition of N in NH3 is 82.35%
