Question

What is the molar mass of calcium?

Answer 1

Step 1: Molar mass

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

Step 2: Formula for molar mass

• $\mathrm{Molar}\mathrm{mass}=\mathrm{The}\mathrm{atomic}\mathrm{mass}\mathrm{of}\mathrm{element}\times \mathrm{number}\mathrm{of}\mathrm{atoms}\mathrm{given}\mathrm{in}\mathrm{subscript}$

Step 3: Molar mass of Calcium $\left(\mathrm{Ca}\right)$

• The molar mass of Calcium is $40.08\mathrm{g}{\mathrm{mol}}^{-1}$.
