Question

What is the molar mass of iron?

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 Iron $\left(\mathrm{Fe}\right)$:

• Iron is a ductile as well as malleable metal.
• It is silver greyish in colour.
• The molar mass of Iron $\left(\mathrm{Fe}\right)$ is $55.85\mathrm{g}{\mathrm{mol}}^{-1}$.
