2. A once-common unit of pressure (still used in the USA) is psi (pounds per square inch). One psi is equivalent to 0.0680460 atm. As you know, the value of the universal gas constant, R, depends on what pressure units you are using. What would be the value of the gas constant incorporating psi as the unit of pressure?

The great French chemist Antoine Lavoisier discovered the law of conservation of mass in part by doing a famous experiment in 1775. In this experiment they found that mercury(II) oxide, when heated, decompose into liquid mercury and an invisible and previously unknown substance: oxygen gas. A. Write a balanced chemical equation, including physical state symbols, for the decomposition of solid mercury (II) oxide (HgO) into liquid mercury and gaseous dioxygen. B. Suppose 72 mL of dioxygen gas are produced by this reaction, at a temperature of 120°C and pressure of exactly 1 atm. Calculate the mass of mercury (II) oxide that must have reacted in grams. Round your answer to three significant digits.
