Question

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

Answer 1

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
