Answer 1

$\fbox\pink{A}\fbox\blue{n}\fbox\purple{s}\fbox\green{w}\fbox\red{e}\fbox\orange{r}$

of atoms in NH₃ = (1 + 3) = 4 x 100/17 x 6.022 x 10²³ = 141.69 x 10²³ atoms. Therefore, NH₃ has more atoms than N₂.

Answer 2

HERE IS YOUR ANSWER MATE

100g of N2 or 100g of NH3. =4.2×1024 atoms. Thus, 100g of NH3 has more number of atoms.
