Given :Weight of N₂= 100gweight of NH₃ = 100g
Molecular mass of N2=28uMolar mass of N2=28g
Molecular mass of NH3 = [14+3x1] =17u
molar mass of NH3=17g
Calculating number of atoms In 100g of N2:
1mole of N2[28 g] Contains -------------> 6.022 x 10²³ moelcules
100g contains -->?
Number of N2 molecules = 6.022 x 10²³x100/28=21.5 moleules Number of N2 atoms =2x21.5=43.0 x 10 ²³
Therefore 100 g of N2 Contains 43x10²³ atoms
Calculating Number of atoms in NH3:
1mole of NH3[17 g] Contains --> 6.022 x 10²³ molecules
100g contains -->? Number of molecules of NH3 = 6.022x10²³ x100/17=35.4 x 10²³ mloecules
As NH3 contains 4 atoms = 4x 35.4 =141.6 x 10²³ atoms∴ 100g of NH3 contains =141.6 x 10²³ atoms
Conclusion:∴100g of NH3 has more atoms than 100g of N2
