Concept Introduction:
Concentration of solution is expressed in terms of molarity. It is the ratio of moles of solute to the volume of solution in litres. The expression used to determine the concentration of solution is as follows:
Mole is the unit that measures the quantity such as atoms, volume and molecules. It is the ratio of given mass to molecular mass of substance. It is expressed as follows:
