Unformatted text preview: 2 2. Explain the difference between molarity and molality. 3. Look up the MSDS of t-butanol. What are the hazards of t-butanol? What first-aid measures should be taken in the event of an accident? 4. Refer to part B in answering this question. As most solutions begin to freeze the solvent freezes out as pure crystals of solid solvent. As a pure substance freezes the temperature remains constant, but as a solvent in a solution freezes out as pure crystals containing no solute the temperature continues to drop gradually. If the temperature of the freezing mixture keeps dropping how do you determine the freezing point of the solvent in the solution?...
