Question 1
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 g (given) i.e., the mass of 1 mole of carbon atoms = 12 g
Then, mass of 6.022×1023 number of carbon atoms = 12 g
Therefore, the mass of 1 atom of carbon = 12(6.022×10²³⁾
= 1.9926×10⁻²³ g
