4. A 200.0mL flask of an unknown gas was placed in a hot water bath. The temperature of the bath was found to be 99°C. The pressure of the flask was 733mmHg. The flask with the unknown gas in it had a mass of 126.593g. The same flask weighed 125.623g when it was empty. Determine the mass of the unknown gas in the flask. Determine the Molar Mass of an unknown gas. Assume that the Ideal Gas Law is obeyed...

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...

Two methods were descibed for determining the volume of the
flask used for the molar mass determination. Which method will give
a more precise determination of the volume? Why?
When two acceptable determinations of the weight of vapor needed to fill the flask have been obtained, remove the foil cover from the flask (do not discard) and clean out the flask. Fill the flask to the very rim with tap water, cover with the foil cover, and weigh the flask,...
