Constants Periodic Table A sample of a liquid substance called jojane- named after the narcissitic scientist Dr. Joey Negdirf who discovered the substance- was brought back to Earth following a five year mission exploring the Andromeda galaxy. In their lab on earth, Dr. Negdirf's team conducted a number of experiments to determine the physical properties of the substance. Part A Using the Dumas method to determine the molar mass of a volatile liquid, a sample of jojane was vaporized in a 2.000 L vessel and heated to 401.6 K at 1.150 bar. The mass of the vapour in the vessel was 5.106 g. Determine the the molar mass of the compound. 60.10 g mol-1 O 88.14 g mol-1 O 72.09 g mol-1 O 74.12 g mol-1
