If one mole of carbon atoms weighs 12 grams, what is the mass (in gram) of 1 atom of carbon?

One mole of carbon atoms weighs 12g (Given)
i.e., mass of 1 mole of carbon atoms = 12g
Then, mass of 6.022× 10²³ number of carbon atoms = 12g
Therefore, mass of 1 atom of carbon = 12/6.022×10²³ g
= 1.9926 × 10⁻²³ g
