If one mole

Answer :

1 mole of carbon atoms means 6.022 × 1023 carbon atoms. In this case 1 mole of carbon atoms weighs 12 grams. This means that the mass of 6.022 × 1023 atoms of carbon is 12 grams.

Now, 6.022 × 1023 atoms of carbon have mass = 12 g


1 atom of carbon has mass = g


= 1.99 × 10-23 g


Thus, the absolute mass of 1 atom of carbon is 1.99 × 10-23 grams.
