The student emptied the same glass-stoppered flask and dried in once again. To the empty flask he added pieces of a metal until the flask was about half full. He then weighed the stoppered flask with the metal contents and found that the mass was 97.327 g. He then filled the flask with water, stoppered it, and obtained a total mass of 118.83 g for the flask, stopper, metal and water. To find the density of the metal the student needs to know the mass and volume of the meyal. However, before he can obtain the volume of the metal, he needs to calculate the volume of the water using the density of water at room temperature. From this calculation, what the volume of the water
