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., mass of 1 mole of carbon atoms = 12 g
Then, mass of $6.022\times {10}^{23}$ number of carbon atoms = 12 g
Therefore, mass of 1 atom of carbon = $\frac{12}{(6.022\times {10}^{23})}$
= $1.9926\times {10}^{-23}$ g
