Problem 3 ( 20pts) A student is attempting to determine the molecular weight of a volatile liquid. The test tube containing the gas held 6.8434 g of water (d=1.008 g/mL). The student evaporated the volatile liquid at 88.00∘C and then condensed the gas in an ice bath. The mass of the condensed gas was 0.01878 g. The atmospheric pressure in the lab was 703.33torr. (a) Determine the volume of the test-tube that contained the gas? (5 pts) (b) How many mols of the volatile liquid filled the test-tube when it was a gas? (10 pts) (c) What is the molecular weight of this compound? (5 pts)
