Molality and Mole Fraction. In Chapter 5 we introduced two important concentration units. % by mass of solute. Molarity. Molality is a concentration unit based on the number of moles of solute per kilogram of solvent. Molality and Mole Fraction. Molality and Mole Fraction.
Molality is a concentration unit based on the number of moles of solute per kilogram of solvent.Molality and Mole Fraction
Boiling point elevation relationship is: moles of solute perBoiling Point Elevation
Freezing Point Depression moles of solute per
Fundamentally, freezing point depression and boiling point elevation are the same phenomenon.
The only differences are the size of the effect which is reflected in the sizes of the constants, Kf & Kb.
This is easily seen on a phase diagram for a solution.Freezing Point Depression
