Previous Year NEET Question- Solution L-2

Question: Which of the following is dependent on temperature?#

A) Molality

B) Molarity

C) Mole fraction

D) Weight percentage

Answer: Molarity#

Solution:#

Molarity and normality are temperature dependent because they involve volume of solutions. Volume is dependent on temperature. $$ \text { Molarity }(M)=\frac{\text { Moles of solute }}{\text { Volume of solution }(\text { in } L)} $$

Molality, mole fraction and weight percentage does not depend on temperature because they involve masses of solute and solvent.
