Rohit Yadav 6 years, 2 months ago

Molality is the ratio of number of moles of solute to the mass of solvent in kg

Yogita Ingle 6 years, 2 months ago

Molarity (M) can be defined as the ratio of number of moles of solute to the volume of solution in liter.
It can also be defined as the number of moles of solute present in unit litre or cubic decimeter of solution.
It is function of temperature due to the dependence of volume on temperature whereas Mass %, ppm, mole fraction and molality are independent of temperature because mass does not depend on temperature.
Mathematically, Molarity = Moles of Solute / Volume of Solution in Litre
