Question

please help!!!!!! What is the mass of 1 mole of magnesium (Mg)? Express your answer to four significant figures. The mass of 1 mole of magnesium is _____ grams

Answer 1

I believe you just look at your periodic table for this value. I don't think there is any math involved.
Therefore one mole of Mg = 24.305g.

Answer 2

Answer: The mass of 1 mole of magnesium is 23.31  grams

Explanation:

Mass of magnesium = x

Molar mass of the magnesium = 24.31 g/mol

Moles = $1 mol=\frac{mass}{\text{Molar mass}}=\frac{x g}{23.31 g/mol}$

Mass of the 1 mole of magnesium:

$x=moles\times text{molar mass}=1 mol\times 23.31 g/mol= 23.31 g$

The mass of 1 mole of magnesium is 23.31  grams
