Sometimes in lab we collect the gas formed by a chemical reaction over water (see sketch at right). This makes it easy to isolate and measure the amount of gas produced. Suppose the O₂ gas evolved by a certain chemical reaction taking place at 30.0 °C is collected over water, using an apparatus something like that in the sketch, and the final volume of gas in the collection tube is measured to be 74.6 mL. 45 Sketch of a gas-collection apparatus collected gas water chemical reaction. Calculate the mass of O₂ that is in the collection tube. Round your answer to 2 significant digits. You can make any normal and reasonable assumption about the reaction conditions and the nature of the gases.

Two students perfomed an experiment on the decomposition of hydrogen peroxide. One student was in Wisconsin where the atmospheric pressure was 0.996 atm. The other was in Colorado, where the atmospheric pressure was 0.832 atm. Both reactions were performed at the same temperature and produced the same number of moles of oxygen gas. How do the volumes of gases collected compare? Are they the same or not? Explain.
