If one mole of carbon atoms weighs 12 gram, what is the mass (in gram) of 1 atom of carbon?
Solution:
One mole of carbon atoms weighs $12 \mathrm{~g}$ (Given)
i.e., mass of 1 mole of carbon atoms = 12 g
One atom of carbon has mass
$=12 \mathrm{~g} \times \frac{1}{6.022 \times 10^{23}}=1.99 \times 10^{-23} \mathrm{~g}$
