NEET 2017 · ChemistryPrevious Year Question
Which of the following is dependent on temperature?
Answer: (B) Molarity. \textbf{Answer:} (B) Molarity \textbf{Solution:} Molarity is defined per unit \textbf{volume} of solution.
- A.Molality
- B.Molarity✓
- C.Mole fraction
- D.Weight percentage
Correct Answer
(B) Molarity
Solution & Explanation
\textbf{Answer:} (B) Molarity \textbf{Solution:} Molarity is defined per unit \textbf{volume} of solution. Volume expands or contracts with temperature, so molarity is temperature-dependent. Molality, mole fraction and weight percentage are all defined in terms of \textbf{mass} (or moles), which do not change with temperature. Hence only molarity depends on temperature.
