Solution

The correct option is D

All of the above


In 7NH3, there are 7 molecules of ammonia. To know the total number of atoms, we need to know the individual number of atoms present and then multiply by 7. So,

Number of N atoms in 7NH3 = 7 × 1 = 7

Number of H atom in 7NH3 = 3 × 7 = 21

Total number of atoms = Number of N atoms + Number of H atoms = 7 + 21 = 28

The total number of atoms present in 7NH3 is 28.
