Unformatted text preview: there is a constant volume then the freezing point is related to number of moles. So the higher the ratio of moles to kg of solvent the greater the change in temperature. The change in freezing point was averaged to be 3.03 C. This correlated to the molecular weight of 32.74. This molecular weight is not close to any of the molecular weights listed in the table of possible unknowns. This is because for one of our trials our solution never froze, it only supercooled. This caused the change in temperature to be much higher than it actually was and forced the molecular weight to be much lower than the actual weight. Other errors could have been poorly calibrated equipment, poorly measured water or unknown weight, or human error in calculations. This experiment forced the student to understand the parts of the change in temperature equation and expanded his or her knowledge in freezing and boiling points...
