If you had a mole of U.S. dollar bills and equally distributed the money to all of the people of the world, how rich would every person be? Assume a world population of 7 billion.

4. Epsom salt is MgSO4 · 7H2O. When heated to 70 to 80°C it loses some, but not all, of its water of hydration. Suppose you heat 2.465 g of Epsom salt to 75°C and find that the mass is now only 1.744 g. What is the formula of the slightly dehydrated salt? Mg SO4 · 6H2O MgSO4 · 5H2O MgSO4 · 4H2O MgSO4 · 3H2O

What is the mass of fish, in kilograms, that one would have to consume to obtain a fatal dose of mercury, if the fish contains 30 parts per million of mercury by weight? (Assume that all the mercury from the fish ends up as mercury (II) chloride in the body and that a fatal dose is 0.20 g of HgCl2.) How many pounds of fish is this?

Consider an iron bar on a balance as shown. As the iron bar rusts, which of the following is true? Explain your answer. a. The balance will read less than 75.0 g. b. The balance will read 75.0 g. c. The balance will read greater than 75.0 g. d. The balance will read greater than 75.0 g, but if the bar is removed, the rust is scraped off, and the bar replaced, the balance will read 75.0 g.
