Question

What is the molar mass of magnesium?

Answer 1

Step1. Molar mass

• The mass of $1$ mole of a substance is called its molar mass.

Step2. Formula for molar mass

Molar mass =$\text{The atomic mass of element × number of atoms given in subscript}$

Step3. Molar mass of Magnesium

• The symbol for magnesium is $\mathrm{Mg}$
• Molar mass of $\mathrm{Mg}$=$24.31{\text{g mol}}^{-1}\text{×1}$

=$24.31{\text{g mol}}^{-1}$

Hence, the molar mass of $\mathrm{Mg}$ is $24.31{\text{g mol}}^{-1}$.
