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.

7.) A glass bulb contains an unknown gas. The gas is either CO2, SO2, C2H6, or CH3F. Here is some data that was collected for this gas sample. Use the data to identify the unknown gas. Mass of glass bulb with the unknown gas: 14.402 g Volume of glass bulb: 670. mL Mass empty bulb 12.232 g Pressure 1751. torr Temperature 21.oC
A sample of gas contains 0.1700 mol of CH4(g) and 0.1700 mol of H2O(g) and occupies a volume of 19.2 L. The following reaction takes place:CH4(g) + H2O(g)3H2(g) + CO(g)Calculate the volume of the sample after the reaction takes place, assuming that the temperature and the pressure remain constant.
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.
13. A barometer is used to measure the total pressure of a mixture of gases A, B, and C. The total pressure is measured to be 750 torr. Assume the partial pressure of gas A is 203 torr and the partial pressure of gas B is 167 torr. What is the pressure of gas C? Do not include units with your answer.
The average molecular speed in a sample of O2 gas at a certain temperature is 447 m/s. The average molecular speed in a sample of CH4 gas is ____m/s at the same temperature.
4. Two containers are attached together as shown with a valve between the containers. The 26.0 L flask contains gas at a pressure of 4.25 atmospheres. The 47.0 L container does not contain any gas. The value between the two containers is opened and the gas in the 26.0 L container then also fills the 47.0 L container. What is the resulting pressure of the gas in the two containers?
