Question

If one mole of carbon atoms weighs 12 grams. What is the mass (in grams) of 1 atom of carbon?

Answer 1

One mole of carbon atoms weighs 12 gram. i.e. 6.022 x 10^23atoms of carbon weigh 12 gram. Therefore, 1 atom of carbon weighs 12 / (6.022 x 10^23) = 1.993 x 10^-23 gram.

Answer 2

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

the molecular mass of carbon atom= 12g

an atom of the carbon mass= 12g

1 atom of the carbon mass= 

12/6.022×10²³g= 1.99×10-²³g
