Question

describe the rast method for determination of relative molecular mass.Also write the equation used giving the significance of the terms involved in it​

Answer 1

PLS MARK BRAINLIEST

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 0.257 g reduces the freezing point of 20.0 g of camphor to 175.9 °C.
