M,Molar mass of NH₃=14+(1×3)=17
m,Given mass=100 g
n,number of moles=m/M=100/17
n=N/N₀
N=n×N₀=(100/17)×6.022×10²³
=3.55×10²⁴

M,Molar mass of NH₃=14+(1×3)=17
m,Given mass=100 g
n,number of moles=m/M=100/17
n=N/N₀
N=n×N₀=(100/17)×6.022×10²³
=3.55×10²⁴
M,Molar mass of N₂=14×2=28
m,Given mass=100 g
n,number of moles=m/M=100/28
n=N/N₀
N=n×N₀
(100/28)×6.022×10²³=2.15×10²⁴
∴Number of molecules in 100 g of NH3 is more than 100 g of N2.
