  1. The same number of moles contain the same number of particles, in this case atoms.

    12 g of C will contain 1 mole of atoms as the molar mass of carbon is 12 g mole^-1 to 2 sig figs.

    So a molar mass of magnesium will contain the same number of atoms. You need to look up the molar mass of Mg.
