You then inverti into the cold water bath at 5.0°C Water enters the flask as the volume of the gas shrinks. a) Theoretically, what should the volume of the gas be after it sits in the cold water bath? b) You find that during your experiment that 65.0 mL of water has entered the flask. What is the experimental volume of the gas? c) What is your percent error for this measurement?
