Balanced equation:
N2 + 3H2 → 2NH3
3 mol H2 will produce 2 mol NH3
You have 1.54*10^-4g H2
Molar mass H2 = 2g/mnol
mol H2 in ( 1.54*10^-4)g = (1.54*10^-4) / 2 = 7.7*10^-5 mol H2
This will produce (7.7*10^-5) *2/3 = 5.13*10^-5 mol NH3 produced
1 mol NH3 contains 6.02*10^23 molecules
5.13*10^-5 mol NH3 contains ( 5.13*10^-5) *(6.02*10^23) = 3.09*10^19 molecules NH3 produced.
