Answer:
Molarity- it is the number of moles of the solute dissolved per litre of the solution.
It is represented by M.
Molarity = moles of solute / volume of solute in litres
Unit for molarity is moles/litre
Molality- it is the number of moles of the solute dissolved per 1000g of the solvent.
It is denoted by m
Molality = mole of solute / mass of solvent in kg
Unit for molality are moles/kg
Mole Fraction - it is defined as the ratio of number of moles of one component to the total number of moles of solute & solvent present in the solution.
Mole fraction = number of moles of the component / total number of moles of all components
It is denoted by x.
