To determine the mass of 1 mole of magnesium (Mg), we need to refer to the atomic mass of magnesium. The atomic mass is a measure of the mass of one mole of atoms of a given element. Therefore, for magnesium, whose atomic mass is known, we can directly state the answer.
The mass of 1 mole of magnesium is 24.305 grams.
Therefore, the mass of 1 mole of magnesium (Mg), expressed to four significant figures, is:
24.31 grams.
