The vapor-pressure lowering upon forming solution can be utilized for determining molecular weight of nonvolatile solutes. Consider a solvent with known P1* and molar mass M1. Upon adding m2 kg of a solute tom1 kg of the solvent, the solution vapor pressure has been measured as P.
(a) Obtain M2 in terms of the specified values the answer should contain only P1*, P,M1, m1,2, presuming an ideal solution.
