Homework Answers
It is displacing 2.79 lb of water, so its volume is
(2.79 lb)/(62.4 lb/ft^3) = 0.0447 ft^3.
Its weight (in air) is 8.05 lb,
so its weight-density is
8.05 lb/(0.0447 ft^3) = 180.1 lb/ft^3

Chemistry exercise: Suppose you have an irregularly shaped solid, known as "metal beads", in a container, that has a mass of 19.3628 g. Then suppose the solid pieces were gently poured into a 25 mL graduated cylinder filled with 4-5mL of water where the solid pieces were completely submerged in the water and the new water level should be < 10mL. What could approximately or possibly be the final volume of water after the metal sample is introduced?

2. A piece of jewelry was tested by method A (Density of Irregularly Shaped Solids by Water Displacement) to determine if it was pure silver or a silver-plated resin. The mass of the jewelry was 1.52 g. A chemist measured the volume displaced by the item, then repeated the experiment. She obtained two different values, 0.16 mL and 0.14 mL. Calculate the density of this item using each volume amount. How do the experimentally obtained density values compare to that...

Someone tries to sell you a solid but irregularly shaped lump of gold, but you are suspicious because you think that it feels too light. Because it is irregularly shaped, you cannot easily calculate its volume from measurable linear dimensions. So this is what you do. You weigh the lump of gold on a pan balance (weight scale) that reads in kg up to a maximum of 80 kg. The scale reading is 25.95 kg with the gold lump resting...
