Question

define molarity and molality.​

Answer 1

Molarity and molality are both measures of the concentration of a chemical solution.

Molarity is the ratio of moles to volume of the solution (mol/L) while molality is the ratio of moles to the mass of the solvent (mol/kg).

Hope this will help you....

Answer 2

Molarity:-

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

Molality:-

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