Question

Define molarity molality normality with which one out of these varies with temperature

Answer 1

molarity and molality are varies with temperature.

Answer 2

As I know that,

Molarity, Molality and Normality are the different terms that are used for representation of concentration of any solution there is slight difference between them. Let us define each term separately :-

Molarity = It is defined as moles of solute / Volume of solution in litre. Ex:- 5M soln of NaCl (aq) means that 5 moles of NaCl is dissolved in 1 litre of water

Molality = It is defined as moles of solute / Mass of solvent in kg. Ex-5 Molal solution of NaCl(aq) means that 5 moles of NaCl is dissolved in 1 kg of water.

Normality :- It is defined as equivalents of solute/volume of soln in litre . You can also denote it by formula molarity* n factor.

Hope it will help.
