The Rast camphor method is a cryoscopic technique for molar mass determination. Exactly 1.00 g of an isoprenoid of known formula (C5H8)n was dissolved in 5.00 g of camphor. The freezing point of the resulting solution decreased by 27.7 ℃ relative to pure camphor. Knowing that the Kf of camphor is 37.7 deg·kg/mol: Calculate for the molar mass of the isoprenoid. Calculate the value of n in the given formula of the isoprenoid. Report in whole number. The normal freezing point of camphor is 178.4 ℃. At what temperature did the isoprenoid-camphor solution freeze?

How to apply Raoult's law to real solutions Consider mixing a liquid with a vapor pressure of 100 torr with an equimolar amount of a liquid with a vapor pressure of 200 torr. The resulting solution would be predicted to have a vapor pressure of 150 torr if it behaved ideally. If, however, the interactions between the different components are not similar we can see positive or negative deviations from the calculated vapor pressure. An actual vapor pressure greater than that predicted by Raoult's law is said to be a positive deviation and an actual vapor pressure lower than that predicted by Raoult's law is a negative deviation.
