a volatile liquid was allowed to evaporate in a 43.298g flask that has a total volume of 252 mL.,the temperature of the water bath was 100 celcius at the atmospheric pressure of 776 torr.the mass of the flask and condensed vapor was 44.173g.calculate the molar mass of the liquid.

Answer 1

PV = nRT
Solve for n = number of moles.

Then moles = g/molar mass. Solve for molar mass.
