Q: Which of the following is a correct unit for molality?
Solution: Molality is defined as moles of solute per kilogram of solvent, hence the unit is mol/kg.
Steps: 5
Step 1: Understand what molality means. Molality is a way to measure the concentration of a solution.
Step 2: Know that molality is defined as the number of moles of solute (the substance being dissolved) in a specific amount of solvent (the substance doing the dissolving).
Step 3: Remember that the unit for moles is 'mol' and the unit for the mass of the solvent is 'kilograms' (kg).
Step 4: Combine these units to express molality. It is calculated as moles of solute divided by kilograms of solvent.
Step 5: Therefore, the correct unit for molality is 'mol/kg'.
