Problem #6: A 12.0 g sample of gas occupies 19.2 L at STP. What is the molecular weight of this gas? Solution: This problem, as well as the two just above can be solved with PV = nRT. You would solve for n, the number of moles. Then you would divide the grams given by the mole calculated. 1) Use PV = nRT: (1.00 atm) (19.2 L) = (n) (0.08206) (273 K)

28 Μαΐ 2020 · A sample of gas isolated from unrefined petroleum contains 90.0% CH 4, 8.9% C 2 H 6, and 1.1% C 3 H 8 at a total pressure of 307.2 kPa. What is the partial pressure of each component of this gas? (The percentages given indicate the percent of the total pressure that is due to each component.) Answer.
Example #7: An ideal gas has a density of 1.17 x 10¯ 6 g/cm 3 at 1.00 x 10¯ 3 atm and 60.0 °C. Identify the gas. Solution: 1) Determine moles of gas in 1.00 L of the sample: PV = nRT (0.00100 atm) (1.00 L) = (n) (0.08206 L atm/mol K) (333 K) n = 0.000036595 mol. 2) The mass of one liter of gas: (1.17 x 10¯ 6 g/cm 3) (1000 cm 3 / 1.00 L) = 1 ...
Example Problems and Solutions. Problem 1: 3 moles of carbon dioxide gas is in an 80-liter fixed cylinder at 320 Kelvin. What is the pressure of the gas? Solution: Given. n = 3. V = 80 L. T = 320 K. From the ideal gas equation, PV = nRT. Or, P = nRT/V. Or, P = 3 M x 0.082 L·atm·M-1 K-1 x 320 K/80 L. Or, P = 0.984 atm
