Step-by-step explanation:
This is a theoretical calculation.
Assuming the 12 gms Magnesium is pure Magnesium.
Molecular weight of Magnesium - 24.305 g/mol
Number of moles of Magnesium in 12 gms - 12/24.305 = 0.49372 moles.
The Avagadro constant defines the number of constituent particles (usually atoms) contained in one mole of a substance - 6.023 x 10^23 (dimensionless)
Number of atoms in 12 gms of Magnesium - 0.49372 x 6.023 x 10^23 = 2.973 x 10^23
