# Given that, Magnesium's one atom's mass is 4.03463*10^-23 g. What is the relative atomic mass of magnesium?

Given mass of 1 atom of Magnesium = $4.03462 \times {10}^{-} 23$ grams; multiply this by $6.023 \times {10}^{23}$ atoms per formula weight => 24.317 grams/formula weight => Relative atomic mass of Mg.
