NEET Chemistry Types of Solutions MCQ Question
Which of the following statements about molarity and molality is correct?
Molarity is temperature-dependent, while molality is independent of temperature.
Both molarity and molality are independent of temperature.
Molarity is defined as mass of solute per volume of solvent.
Molality is defined as the number of moles of solute per liter of solution.
Correct Answer
Detailed Explanation
Molarity (M) is defined as moles of solute per liter of solution and is temperature-dependent, while molality (m) is defined as moles of solute per kilogram of solvent and is independent of temperature, as stated in the NCERT context.
