You weigh a dry flask, and place a chunk of solid into it, then weigh it again. You then fill the flask to the top with water and weigh the full flask. Finally, you take the solid out, fill the flask to the top with water and weigh it once more. Mass of flask in (g) 58.5591 Mass of flask plus solid (g) 134.2642 Mass of flask plus solid and water (g) 142.3225 Mass of flask filled with water (g) 83.8179 Density of water at the measured water temperature (g/cc) 0.9946 Calculate the following: The mass of the solid in (g)
