if the freezing point of the solution had been incorrectly determined to be lower than the true freezing point, how would that affect the calculated molar mass? Explain.

The molecular weight would be higher if the true freezing point is bigger than the determined freezing point. It’s higher because ....

delta T = Kf*m
m = mols/kg solvent
mols = g/molar mass.

If delta T is too large, molality will be to large.
If molality is too large, mols will be too large.
If mols is too large, then molar mass will be too small.(from molar mass = g/mols).
