density 22.3= 1.1367
A student takes the flask in problem 1, after it has been emptied, cleaned, and dried. The student then added chunks of an unknown solid to the flask and found that the mass of the flask with solid was 330.2117 g. Leaving the solid in the flask, the student added some water at 22.3 degree C until the flask was completely filled. The mass of the flask with solid and water was 418.1522 g. Determine the density of the unknown solid. A student is asked to determine the density of an unknown liquid using the method in part B of this experiment. The student finds that the mass of an empty container is 21.6119 g. The student then pipettes 20.00 mL of the unknown liquid into the container and finds that the mass of the container plus liquid is 57.2911g. Determine the density of the unknown liquid.
