Dichloromethane (CH2Cl2) has a density of 1.33 g/mL. What volume of vapor would be generated by the vaporization of 2.00 ml of dichloromethane at 100C? What mass of dichloromethane (CH2Cl2) vapor would fill a flask with a volume of 139 mL at 100C and 760 torr? From the following data, calculate the molar mass of the unknown liquid: Initial mass of flask = 89.541 g Mass of flask + condensed vapor = 89.957 g Volume of flask = 155 mL
