Question

What is the relationship between the number of moles (n) and molar mass (m) of a substance?

Answer 1

Relationship between the number of moles (n) and molar mass (m) of a substance:

Molar mass (m): Molar mass of a substance is the mass of one mole of a substance or it is the mass of $6.022\times {10}^{23}$ particles of that substance.

• It is expressed in gram per mol (g mol^-1)

By knowing the molar mass of a substance, number of moles of that substance can be calculated in a given mass of that substance.

• Relationship between number of moles (n) and molar mass (m) of a substance is as follows:
• $\mathrm{Number}\mathrm{of}\mathrm{moles}\left(\mathrm{n}\right)=\frac{\mathrm{Given}\mathrm{mass}}{\mathrm{Molar}\mathrm{mass}\left(\mathrm{m}\right)}$
