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

 

Answer

Given,

Mass of 1 mole of Carbon  = Molar mass of C = 12g

1 mole of carbon = 6.022 x 10 23 atoms of Carbon

Therefore,

Mass of 6.022 x 10 23 atoms of Carbon = 12 g

Mass of 1 atom of Carbon = 12 / 6.022 x 10 23

                                            ≈ 2 x 10 - 23 g
