What is the relationship between the moles of solute and the
mass of solute?
Rewrite the molality expression in terms of grams and molecular
weight.
Background:
Properties that depend on the concentration of particles in solution are called colligative properties. The number of particles in a solvent can affect the freezing or boiling point of solvent. To express the effect of concentration on freezing point or boiling point, molality is used in place of molarity. Molality (m) is the number...
