WebMeasuring concentration using moles per liter (moles/L) is more useful in chemistry than using grams per liter because it tells you how many particles of a substance you’re dealing with. We call the measure of moles per liter of solution the molarity. WebFreezing point depression is the phenomena that describes why adding a solute to a solvent results in the lowering of the freezing point of the solvent. When a substance starts to freeze, the molecules slow down due to the decreases in temperature, and the intermolecular forces start to take over. WebMay 12, 2014 · The 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 … Molality is a measurement of the concentration of a solution by comparing … gros hippocampe
