The U.S. Mint produces a dollar coin called the American SilverEagle that is made of nearly pure silver. This coin has adiameter of 41 mm and a thickness of 2.5 mm. The densityand approximate market price of silver are 10.5 g/cm3 and$0.51 per gram, respectively. Calculate the value of the silverin the coin, assuming its thickness is uniform.

A materials engineer has filed for a patent for a new alloy to be used in golf club heads. The composition by mass ranges from 25 to 31% manganese, 6.3 to 7.8% aluminum, 0.65 to 0.85% carbon, and 5.5 to 9.0% chromium, with the remainder being iron. What are the maximum and minimum percentages of iron possible in this alloy? Use Figure 2.12 to snake a prediction about how the density of this alloy would compare with that of iron; justify your prediction.
Calculate the average density of a single Al-27 atom by assuming that it is a sphere with a radius of 0.143 nm. The masses of a proton, electron, and neutron are 1.67261024g,9.10941028g, and 1.67491024g, respectively. The volume of a sphere is 4r3/3, where r is its radius. Express the answer in grams per cubic centimeter. The density of aluminum is found experimentally to be 2.70 g/cm3. What does that suggest about the packing of aluminum atoms in the metal?
A general chemistry student found a chunk of metal in the basement of a friends house. To figure out what it was, she used the ideas just developed in class about density. She measured the mass of the metal to be 175.2 grams. Then she dropped the metal into a measuring cup and found that it displaced 15.3 mL of water. Calculate the density of the metal. What element is this metal most likely to be?
The U.S. Mint produces a dollar coin called the American Silver Eagle that is made of nearly pure silver. This coin has a diameter of 41 mm and a thickness of 2.5 mm. The density and approximate market price of silver are 10.5 g/cmand $0.51 per gram, respectively. Calculate the value of the silver in the coin, assuming its thickness is uniform.
Bromine is used to prepare the pesticide methyl bromide andflame retardants for plastic electronic housings. It is recoveredfrom seawater, underground brines, and the Dead Sea. The aver-age concentrations of bromine in seawater (d=1.024 g/mL) andthe Dead Sea (d=1.22 g/mL) are 0.065 g/L and 0.50 g/L, re-spectively. What is the mass ratio of bromine in the Dead Sea tothat in seawater?
