3.107 As computer processor speeds increase, it is necessary for engineers to increase the number of circuit elements packed into a given area. Individual circuit elements are often connected using very small copper “wires” deposited directly onto the surface of the chip. In some processors, these copper interconnects are about 22 nm wide. How many copper atoms would be in a 1-mm length of such an interconnect, assuming a square cross section? (The density of copper is 8.96 g/cm3.)

Two general chemistry students working together in the lab weigh out 0.832 g of CaCl2 2 H2O into a crucible. After heating the sample for a short time and allowing the crucible to cool, the students determine that the sample has a mass of 0.739 g. They then do a quick calculation. On the basis of this calculation, what should they do next? (a) Congratulate themselves on a job well done. (b) Assume the bottle of CaCl2 2 H2O was mislabeled; it actually contained something different. (c) Heat the crucible again, and then reweigh it.

Calomel, Hg2Cl2, is a compound composed of the diatomic ion of mercury(I), Hg2 2+, and chloride ions, Cl–. Although most mercury compounds are now known to be poisonous, eighteenth-century physicians used calomel as a medication. Their patients rarely suffered any mercury poisoning from the treatments because calomel is quite insoluble:Hg2 Cl2(s) ⇌ Hg2 2+(aq) + 2Cl−(aq) Ksp = 1.1 × 10−18Calculate the molar solubility of Hg2Cl2.
Cocaine (C17H21O4N; Figure 2) is a natural substance found in leaves of the coca plant, which have been used for centuries as a local anaesthetic and stimulant. Illegal cocaine arrives in the USA either as the pure compound or as the hydrochloride salt (C17H21O4NHCl). At 25oC, the salt is very soluble in water (2.50 kg/L), but pure cocaine is much less so (1.70 g/L). What is the maximum amount of the salt (in gram) that can dissolve in 50.0 mL of water? When a 25 mL aqueous solution that contains 62.50 g of the salt is treated with NaOH, the salt is converted to pure cocaine. How much water (in litres) is needed additionally to dissolve the formed pure cocaine? Round your final answer off to two decimal points.
