Question

Accepted Answer

Normality, molarity, molality, and molarity are different units of concentration used in chemistry.

Normality is a measure of the concentration of a solute in a solution based on its equivalent weight.
Molarity is a measure of the concentration of a solute in a solution based on the number of moles of solute per liter of solution.
Molality is a measure of the concentration of a solute in a solution based on the number of moles of solute per kilogram of solvent.
Molarity is similar to molality, but it is based on the volume of the solution rather than the mass of the solvent.

Accepted Answer

Molality is ratio of the moles of solute to the kilogram of solvent.

The number of gram equivalent weight of a solute into one litre of a solution is called as Normality.

Molarity is moles of solute to the volume of solution in litre.

Accepted Answer

Normality:

It is number of gram equivalents of solute dissolved per litre of a solution.

It's unit is g equivalents Litre

Molality:

It represents by letter 'm'.

The number of gram mole of the solute present in 1000g of the solvent is known as molality of solution.

Molarity (M):

Molarity is most common units of concentration of solution.

It is defined as the number of moles of solute present in one litre of solute present in one mL of solution.
