What does molality measure?

O

A. Kinetic energy

O

B. Density

C. Concentration

D. Temperature change

Molality measure C. Concentration

Explanation:

Molality is used to measure concentration of solute molecule present in a solution. Molality represent the presence of total number of solute molecules in a kilgram of solvent.

For exam if 6 moles of a solute is present in 1 kg of solvent then the concentration of that solute molecule will be 6 molal. The SI unit of molality is mole/kg or milimole/gram.
