1. what is the temperature of .49 mol of gas at a pressure of 1.2 atm and a volume of 12.4 L? 2. A weather balloon is inflated to a volume of 26.1 L at a pressure of 755 mmHg and a temperature of 23.0. C The balloon rises in the atmosphere to an altitude, where the pressure is 375 mmHg and the temperature is -16.9. C assuming that that balloon can freely expand, calculate the volume of the balloon at this altitude in L. 3. To identify a diatomic gas (X2), a researcher carried out the following experiment: She weighed an empty 5.8-L bulb, then filled it with the gas at 1.30 atm and 22.0C and weighed it again. The difference in mass was 8.7g . Identify the gas. 4. A 1-L flask is filled with 1.30g of argon at 25C . A sample of ethane vapor is added to the same flask until the total pressure is 1.00 atm. What is the pressure of argon Par in the flask? What is the partial pressure of ethane, Pethane, in the flask? 5. 14.0 moles of gas are in a 5.00 L tank at 23.4 C. Calculate the difference in pressure between methane and an ideal gas under these conditions. The van der Waals constants for methane are a=2.300 L2*atm/mol2 and b=0.430L/mol
