Having obtained the volume of a flask (25.001 mL), the student then emptied the flask and dried it. The mass of the empty stoppered flask was 25.710 g. To the empty flask they added pieces of a metal until the flask was about three-fourths full. The student weighed the stoppered flask and its metal contents and found that the mass was 162.071 g. They then filled the flask with water, stoppered it, and obtained a total mass of 167.932 g...
