Finding mass with molarity and volume
WebQuestion: In the 19th century, J. B. A. Dumas devised a method for finding the molar mass of a volatile liquid from the volume, temperature, pressure, and mass of its vapor. He placed a sample of such a liquid in a flask that was closed with a stopper fitted with a narrow tube, immersed the flask in hot water bath to vaporize the liquid, and then cooled the flask.
