Answer 2

Given: 1 mole of ammonia.

To find: We have to find the number of atoms.

Solution:

The number of atoms of 1 mole of ammonia can be calculated by the following steps-

The molecular mass of ammonia is 17u.

The molecular weight of ammonia is 17 grams.

We know that 1 mole or 17u or 17g of ammonia contains $6.023×20^{23}$ number of atoms.

Thus the number of atoms present in 1 mole of ammonia is $6.023×20^{23}$.
