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 35.0 °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 117. mL. g collected X gas water chemical Sketch of a gas-collection apparatus 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. reaction

Three gases are mixed into one container. The partial pressure of gas D is 820.1 mmHg. The partial pressure of gas E is 217 mmHg. The partial pressure of gas F is 445.3 mmHg. Determine the total pressure of the gases in a different unit, atm. Do not round until you have finished the problem. 1.00 atm = 760.0 mmHg Your answer should contain one decimal place. Ex: If your answer is 4.435, you would use 4.4 Include the correct units.
Part B A sample of gas in a cylinder as in the example in Part A has an initial volume of 64.0 L, and you have determined that it contains 1.10 moles of gas. The next day you notice that some of the gas has leaked out. The pressure and temperature remain the same, but the volume has changed to 16.0 L. How many moles of gas (m₂) remain in the cylinder?

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.
