Prepare For It! Prelab Question A student weighs a flask, foil cover, and rubber band and finds the mass is 74.95 g. He then adds about 5 mL to the flask and then heats the flask in a boiling water bath (100.0°C) to evaporate all of the volatile liquid. Once the flask is removed from the water bath and cooled, the collected gas condenses into a liquid. The mass of the flask, foil cover, rubber band, and condensed liquid is...
