One atom of an unknown element is found to have a mass of 4.480 × 10^−23g. What is the molar mass of this element?


Molar mass has units of g/mol. We are given mass of one atom, 4.480 × 10^−23g/ 1 atom. We need to use Avogadro's number to convert atoms to moles (6.0221408*10^23 atoms/mol).


4.480 × 10^−23g * 6.0221408*10^23 atoms = 26.98 g/mol

1 atom 1 mol
