Question
if the freezing point of the solution is recorded 0.2 degrees C lower than the actual freezing point, will the molar mass determination for the unknown solid be too high or too low?

it will appear that there are more moles of solute than are actually present
you will be dividing the mass of added solute by too large a number
... this will result in the molar mass being too low
