1. If the freezing point of the solution is recorded 0.2°C lower than the actual freezing point, will the molar mass determination for the unknown solid be too high or too low? Explain. 2. If a thermometer is miscalibrated to read 0.5 °C higher than the actual temperature over its entire scale, how will it affect the reported molar mass of the solute? Explain.

Question
1. If the freezing point of the solution is recorded 0.2°C lower than the actual freezing point, will the molar
mass determination for the unknown solid be too high or too low? Explain.
2. If a thermometer is miscalibrated to read 0.5 °C higher than the actual temperature over its entire scale,
how will it affect the reported molar mass of the solute? Explain.
3. Cyclohexane has a relatively high vapor pressure. If some of the cyclohexane evaporates during the
experiment, how will this affect the AT? How will this affect the reported molar mass of the unknown
solute? Explain.
4. Why was a salt/ice bath used in this experiment instead of just an ice bath?
