Answer :


The number of atoms =

N = × N0


The number of molecules in 100g of N2:


Atomic mass of nitrogen (N) = 14


Molar mass of N2 molecules = 14x2 = 28g



Number of atoms in N2 = 1 + 1 = 2


= 2 X = 43.01X 1023


The number of molecules in 100g of NH3:


Molar mass of NH3 molecules = 14+3X1 = 17g



number of atoms in NH3 = 1 + 3 = 4


= 4 X


Therefore, NH3 would have more atoms.
