Suppose you have a stoppered ?ask containing CO2 gas at room temperature and pressure. If the volume of your stoppered ?ask is 300.0 mL, the pressure in the room is 770 mm Hg, and the temperature in your work area is 22.0°C, how many moles of CO2 are in the ?ask? Remember: PV = nRT (keep track of units!)
a) How many grams of CO2 are in the ?ask (described in part b)?
b) Why do we measure the volume of the ?ask with water rather than using the volume listed on
the side?
c) Why is the ?ask not ?rmly stoppered during sublimation?
