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 sample of cocaine, C17H21O4N, is diluted with sugar, C12H22O11. When a 1.00-mg sample of this mixture is burned, 1.00 mL of carbon dioxide (d=1.80g/L) is formed. What is the percentage of cocaine in this mixture?
2.95 Engineers who design bicycle frames are familiar with the densities of aluminium (2.699 g/cm3), steel (7.87 g/cm3), and titanium (4.507 g/cm3). How does this information compare with Figure 2.12, and what would it suggest for changes in this figure if more shades were used for the density colour-coding? (Iron is the principal component of steel)
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.
You take three compounds, each consisting of two elements (X, Y. and/or Z), and decompose them to their respective elements. To determine the relative masses of X, Y. and Z. you collect and weigh the elements, obtaining the following data: Elements in Compound Masses of Elements 1. X and Y X = 0.4 g, Y = 4.2 g 2. Y and Z Y = 1.4 g, Z = 1.0 g 3. X and Y X = 2.0 g, Y = 7.0 g a. What are the assumptions needed to solve this problem? b. What are the relative masses of X, Y. and Z? c. What are the chemical formulas of the three compounds? d. If you decompose 21 g of compound XY, how much of each element is present?

(a) Palladium (Pd) is an element with properties similar to those of platinum. It is useful in eliminating harmful emission produce by internal combustion engines. Two students were given identical cylindrical “palladium” bars with the following data: Mass = 96.03 g; Length = 10.7 cm; Diameter = 9.82 mm; Density = 12.02 gcm-3 Show the calculations that Student K and S would do if: Student K was asked to determine whether his bar was made of pure palladium. Student S was asked to calculate the grams of ethyl alcohol (d = 0.789 gcm-3) his bar would displace.
