Question

What is the advantage of molarity over molality as the unit of concentration??

Answer 1

Both are used to calculate the number of moles of solute. But By using molality term we can calculate number of moles of solutes in solvent, so it gives the advantage of knowing the number of moles of solute in solvent while in molarity we can only calculate number of moles of solute in solution ( per litre).

⟹ Advantage of molarity over molality as the unit of concentration :-

• Both are used to calculate the number of moles of solute.
• By using molality term we can calculate number of moles of solutes in solvent, so it gives the advantage of knowing the number of moles of solute in solvent while in molarity we can only calculate number of moles of solute in solution ( per litre).
