How does molality affect freezing point
WebDec 7, 2024 · The difference between them and the correct application for each term. Both molality and molarity are units of concentration. Molality is used when temperature changes are expected. Rafe Swan, Getty Images. Molality (m) and molarity (M) both express the concentration of a chemical solution. Molality is the number of moles of solute per … WebThe more concentrated a solution, the more the freezing point of water will be depressed. The solute particles basically interfere with the ability of the water molecules to freeze because they get in the way and make it more difficult for the water to hydrogen bond.
