NEET Chemistry (general) MCQ Question
Type: MCQ-conceptual-Easy-Class 12
Which of the following statements about the components of a solution is correct?
A
The total vapor pressure of a solution is the sum of the partial pressures of its components.
B
Molarity is defined as the total mass of solute divided by the volume of the solution.
C
The mole fraction of a component in a solution can be greater than 1.
D
Vapor pressure of a solution is always higher than that of the pure solvent.
Correct Answer
Option A
Detailed Explanation
The total vapor pressure of a solution is indeed the sum of the partial pressures of its components, as indicated by Dalton’s law of partial pressures. Molarity is defined as moles of solute per liter of solution, and mole fractions can never exceed 1.
