Molarity is defined as the number of moles of substance dissolved in per liter of solution (moles/Liter). It is also called molar concentration of the solution.

Molality is defined as the number of moles of substance dissolved in one kg or kilogram of solvent and its SI unit is mol/kg.

Density is defined as the mass divided by its volume.

density =mass/volume

Weight percent is defined as the division of mass of a solute to the mass of the total solution, multiplied by 100. To calculate the weight percent or mass percent, both mass of a solute and the mass of a solution is required to express the concentration of a solution.

Volume percent is defined as the ratio of the volume of the solute to the volume of the total solution multiplied by 100.
