The number of electrons in given amount of ammonia are 5.66\times 10^{24}

Explanation:

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Given mass of ammonia = 16 g

Molar mass of ammonia = 17 g/mol

Putting values in above equation, we get:

\text{Moles of ammonia}=\frac{16g}{17g/mol}=0.941mol

The chemical formula of ammonia is NH_3

Number of electrons in nitrogen atom = 7

Number of electrons in hydrogen atom = 1

Total number of electrons = [7 + 3(1)] = 10

According to mole concept:

1 mole of a compound contains 6.022\times 10^{23} number of particles

So, 0.941 moles of ammonia will contain = (0.941\times 10\times 6.022\times 10^{23})=5.66\times 10^{24} number of electrons
