Would the experimental MW be greater than or less than the true value if: a) Your sample was not fully vaporized? b) The actual barometric pressure was substantially lower than the reading you used? c) Your final weighing did not include the weight of the rubber band, because it broke? What would be the calculated MW of an unknown volatile liquid if the following values were obtained? Show your calculations. Temperature of water bath = 101.5 °C Barometric pressure = 75.07 cm Hg Volume of flask = 124.4 mL Mass of condensed sample = 197 mg Would the experimental MW be greater than or less than the true value if: a) Your sample was not fully vaporized? b) The actual barometric pressure was substantially lower than the reading you used? c) Your final weighing did not include the weight of the rubber band, because it broke?
