Text solutionVerified

1.4 g of nitrogen corresponds to

\frac{1.4}{28} = 0.05

moles.

0.05 moles of nitrogen corresponds to

0.05 \times 6.023 \times 1 0^{23} = 3.011 \times 1 0^{22}

molecules.

One molecule of nitrogen contains 14 electrons.

1.4 g of nitrogen will contain

3.011 \times 1 0^{22} \times 14 = 4.2154 \times 1 0^{23}

electrons.
