Question

Calculate number of atoms present in 170g NH3

Answer 1

Answer:

So 4.25 g ammonia will contain (6.022×10^23×4.25)/17 = 1.5×10^23 number of ammonia molecules. Each molecule contain 4 atoms (1 N atom

and 3 H atoms). So 4.25g ammonia will contain 1.5×10^23×4 = 6×10^23 number of atoms. number of atoms in 4.25/17 =0.25 mol of nh3.
