How is molality (m) defined?

Options

  1. AMolality is the number of solute molecules in one kilogram of solution.
  2. BMolality is the number of moles of solute per kilogram of the solvent.
  3. CMolality is the number of moles of solute per liter of solution.
  4. DMolality is the number of moles of solute per milliliter of solution.

Correct answer

B. Molality is the number of moles of solute per kilogram of the solvent.

Step-by-step solution

The paragraph provides the definition of molality as the number of moles of solute per kilogram of the solvent.
