$\huge\blue{Number of molecules in ammonia :-}$

MOLAR mass of Ammonia = NH3 =14 + 1×3=17g/mol

Moles of Ammonia = Mass/molar mass

Moles of ammonia =100/17

Moles of ammonia = 5.8mol

Moles of ammonia = number if molecules of NH3/Avagadro number

Number of molecules of ammonia = Moles of NH3 × avagadro number

Number of molecules of NH3b= 5.8 ×6.023×10^23

Number of molecules of ammonia = 34.9 ×10^23

----------------------------------------------------------------------

$\huge\green{Number of molecules of N2:-}$

Mass/molar mass=number of molecules /avagadro number

Number of molecules = mass/molar mass×avagadro number

Number of molecules of N2 = 100/28×6.023×10^23

Number of molecules of N2=3.57×6.023×10^23

Number of molecules of N2 = 21.5×10^23

------------------------------------------------------------

So.........

Molecules of ammonia in 100g are more than molecules of N2 in 100g
