Question

If one mole of carbon atom weighs 12g what is the mass of 1 atom of carbon

Answer 1

1 mole of carbon atom = 12g

1 mole of a carbon atoms = 6.022$\times {10}^{23}$atoms

Hence, mass of 6.022$\times {10}^{23}$atoms of carbon = 12g

Mass of 1 atom of carbon =$\frac{12}{6.022\times {10}^{23}}$ = 1.9$\times {10}^{-23}$g
