A student produced a volatile liquid experiment with the following results:

Mass of flask, boiling water, foil cap, and unkown after cooling, g: 83.350
Mass of flask, boiling stone, and foil cap, g: 82.657
Water bath temperature: 95*C
Barometric pressure: 30.09 in. HG
Volume of flask: 270 mL
Accepted molar mass of unkown, g mol-1: 86.2

What is the density of the vaporized unkown?

What is the molar mass of the vaporized unkown?



Thank you!
