1. the rast method for determining molar masses uses camphor as the solvent. camphor melts at 178.4 °c, and its large kf (37.7 k kg mol-1) makes it especially useful for accurate work. a sample of an unknown substance that has a mass of 0.664 g reduces the freezing point of 25.0 g of camphor to 173.6 °c.
what is the molar mass of the unknown compound?
