Answer:4.25 g ammonia will contain (6.022×10^23×4.25)/17 = 1.5×10^23 number of ammonia molecules.

Explanation: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

Molecular mass of NH3 is 17g.

moles of NH3 = 4.25/17

= 0.25

No. of molecules = 0.25× 6.02× 10²³

= 1.505×10²³

No. of atoms in NH3 = 4×1.505×10²³

= 6× 10²³. (approx)
