In one mole of magnesium there are 6.022 x 1023 atoms. Mole of a substance is equal to the ratio of number of atoms given to Avogadro's number.
Moles = Number of atoms / Avogadro's numbers
Moles = 1.56 x 1021 atoms/ 6.022 x 1023 atoms
Moles = 0.26 x 10-2 approx
Mole of a substance is equal to the ratio of mass to molar mass. The molar mass of magnesium is 24 grams per mole.
Moles = mass/ molar mass
Mass = Mole* Molar mass
Mass = 0.26 x 10-2 x 24
Mass = 6.21 x 10-2 grams
