We set up an experiment utilizing the Dumas method to calculate the molar mass of an unknown chemical. A 4.00mL pure liquid sample of this chemical is vaporized in an Erlenmeyer flask with a volume of 155 mL, when the barometric pressure is 1.01 atm. The empty flask weighs 25.2436 g. After the excess gas escapes, the temperature is measured as 97.0±C. The flask and contents are subsequently cooled and the vapor condenses to a liquid. The weight of the flask and contents is found to be 25.7843 g. Calculate the molar mass of the unknown liquid.
