In an experiment as described in the Principles section, 158 mL of O2 is collected over water. The mass of the O2 is measured to be 0.207 g, the temperature is 290 K and the barometric pressure that day is 754 mm Hg. Calculate the value of R in the units L, atm, K, mol. Remember: The pressure measured is the pressure of a mixture of water vapor and the gas we are interested in, O2. To correctly calculate the partial pressure of O2, the vapor pressure of the water must be accounted for. There is a table of vapor pressures of H20 at different temperatures in your lab manual. Enter your answer in the box below. You do NOT need to include units, but your answer should be expressed in L'atm/mol·K.

Effusion is the process where a gas flows through a small hole in a container. Graham’s Law of Effusion says that the rate of effusion of a gas from a particular hole is inversely proportional to the square root of the MW of the gas (at constant temperature and pressure). Describe why normal balloons filled with He tend to go flat faster than the same balloons filled with air.
Find the temperature in ˚ C of 0.792 moles of hydrogen gas with a volume of 18639 mL collected at a 761.88 torr. The gas was not collected over water.The ideal gas constant, R = 82.1 atm·mL/mol·K.The ideal gas equation is: PV=nRT
The number of moles of CO2 in that last equation was 0.119 moles.

An effusion container is filled with 2 L of an unknown gas. It takes 400 s for the gas to effuse into a vacuum. From the same container under the same conditions--same temperature and initial pressure, it takes 161 s for 2.00 L of O2 gas to effuse. Calculate the molar mass (in grams/mol) of the unknown gas.
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 CO₂ gas evolved by a certain chemical reaction taking place at 55.0 °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 129. mL. g x10 177 Sketch of a gas-collection apparatus x collected gas Calculate the mass of CO₂ 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. water chemical reaction
