Detailed Solution

Normality of the solution decreases with increase of temperature, since volume of the solution is directly proportional to temperature.

Normality=wGEW×1000Vinml

Normality1V .

Mass – Mass percentage ((W/W):

Mass percentage=(mass of solutemass of solution)×100

W%=(WW+W)×100

Molality: The number of moles of the solute present in one Kg (or) 1000g of the solvent.

m=WGMW×1W(Kg)    (or) m=WGMW×1000W(g)

Mole fraction: The ratio between the number of moles of a component of the solution to the total number of moles of all components of the solution is called mole fraction of that component.

Then, mle fraction of solute A is given by  XA=nAnA+nB  similarly, mole fraction of the solvent B in a solution is

XB=nBnA+nB

The sum of the mole fractions of all the components in the solution is equal to unity.

XA+XB=1

Hence molality, mole fraction and mass percentage these are independent of temperature.
