First You convert 645.0 torr to atm, and also mL to L. You use PV=nRT, to find the number of moles. Then you use the number of moles to get the molar mass. mol= mass/molar mass
Now suppose, instead, that the solute in problem 6 is volatile and that the pure solute displays, at 90 oC, a vapour pressure of 52.580 torr. Calculate the molar mass (in g) for this case. This is the second part to this question
I finally got it right..
