Question

Relation between molarity and molality

Answer 1

Molarity is number of moles of a solute in 1L of a solution. Molality is number of moles of a solute in 1 kg of the solvent in the solution. While normality is the product of Molarity and n-factor. For acids, n-factor is defined as the number of H+ions replaced by 1 mole of acid in a reaction.

Answer 2

Answer:

Molarity (M) is defined as the number of moles of solute per liter of solution.

Molality (m) is defined as the number of moles of solute per kilogram of solvent.
