Question

Which of the following changes with increases in temperature:

• A. Molrity
• B. Weight fraction of solute
• C. % w/v of solute present in water
• D. Mole fraction

Answer 1

The correct option is A Molrity

Temperature will affect the volume of the solution

We have molarity= $\frac{\text{Number of moles}}{\text{Volume in L}}$

Hence, molarity changes with the temperature. With increase in temperature, volume will increase & then molarity will decrease.
