2.00 g of an unknown volatile liquid was placed in a flask with a total volume of 265.0 ml. the cover of the flask has only a pinhole, which allows the internal pressure to equilibrate with the outside pressure. the temperature was raised to 100.00c by placing the flask in a constant temperature water bath. at this temperature, it was found that only 0.581 g of the liquid substance remained in the flask. a barometer in the lab showed the pressure to be 752 mm hg. what's the molar mass of the unknown liquid?
