Question

For an infinitely dilute aqueous solution, molality will be equal to:

• A. formality
• B. molarity
• C. mole fraction
• D. ppm

Answer 1

Answer: (B)

molarity

For an infinitely dilute aqueous solution, molality will be equal to molarity. Its volume will be equal to its mass.
Thus, $1$ L of solution will weigh $1$ kg.
The number of moles of solute per litre of solution will be equal to the number of moles of solute per kg of solution.
