Molecular Mass by Freezing point Depression (Preliminary Lab) The following errors occurred when the above experiment was carried out. How would each affect the calculated molecular mass of the solute (too high, too low, no effect)? Explain your answer.
(a) The thermometer uses actually read 1.4C too high.
(b) Some of the solvent was spilled before the solute was added.(c) Some of the solute was spilled after it was weighed and before it was added to the solvent.(d) Some of the solution was spilled after the solute and solvent were mixed but before the freezing point was determined.
