A student received a sample of an unknown liquid, which is then vaporized in a flask having a volume of 250 mL at 80.7 °C. The vapor has a mass = 0..7179 g, and exerts a pressure = 753 torr. Using the following list of volatile liquids, determine which one is the sample examined by the student.

Possible samples:

Methanol (CH4O)

Isopropanol (C3H8O)

Ethyl acetate (C4H8O2)

Cyclohexane (C6H12)

Acetone (C3H6O)

A student was assigned the task of determining the identity of an unknown liquid. The student weighed a clean, dry 250-mL Erlenmeyer flask. The student completely filled the flask with water. He then proceeded to weigh the flask containing the water. Mass of 250-mL Erlenmeyer flask: 78.639 g Mass of 250-mL Erlenmeyer flask and water: 327.039 g Assuming the density of water is 1.00 g/mL at ambient temperature, what is the exact volume (in mL) of the 250-mL Erlenmeyer flask?...
