• First, students will review what happens when a liquid freezes and when it boils.
• Then, a discussion about how adding a nonvolatile solute would affect the freezing and boiling process.
• Molality will be introduced followed by practice problems.
• The freezing point depression and boiling point elevation formulas will be introduced with examples for students to work out.
• Finally, a practical investigation to work out the molar mass of an unknown solute by using freezing point depression will be outlined with an example calculation. (This lab activity is available in a separate resource).
