Question

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) 56.0653 Mass of flask plus solid (g) 134.3385 Mass of flask plus solid and water (g) 143.4133 Mass of flask filled with water (g) 84.1648 Density of water at the measured water temperature (g/cC) 0.9950 Calculate the following: Density of the solid unknown in (g/cc) Answer

Explanation / Answer

Mass of solid = Mass of flask plus solid - mass of flask

Mass of solid = 134.3385 g - 56.0653 g = 78.2732 g

Mass of water = 84.1648 g - 56.0653 g = 28.0995 g

Volume of water = 28.0995 g / 0.9950 g/cc = 28.2407 cc

Density of solid unknown = 78.2732 g / 28.2407 cc = 2.772 g/cc

Density of solid unknown = 2.772 g/cc
