Question 4. Option A
Question 5. 1.10 bar
Explanation: P = RT/(V-b) - a/V2 = 0.0821*303/(22.7-0.0466) - 8.33/22.72 = 1.082 atm = 1.10 bar (1 atm = 1.01325 bar)
Question 6. Xe
Explanation: Xe is the monoatomic noble gas/inert gas, which will behave closest to an ideal gas.

Part A) Which of the following statements is true for ideal gases, but is not always true for real gases? Choose all that apply. Molecules are in constant random motion. Pressure is caused by molecule-wall collisions. The size of the molecules is unimportant compared to the distances between them. The volume occupied by the molecules is negligible compared to the volume of the container. Part B) Which of the following statements is true for real gases? Choose all that apply....
Oxygen gas (O2) is stored in steel cylinders. Assume we have 95.4 mol O2 stored in a 28-L cylinder at 25 oC. Use the van der Waals equation to calculate the pressure (in bar). [for O2(g), a = 137.8 and b = 0.0318]

3. According to the publication NFPA58, a 20 lb (9.09 kg) propane (C3H8) tank at 76°F (25°C) would have a pressure of 150 psig (10.3bar). Determine the internal volume in Liters of the tank using i) van der Waals EOS, and ii) SRK EOS. For propane van der Waals constants are a= 9.385 bar L/mold and b = 0.09044 L/mol. In addition, Tis 369.9 K, PC is 42.Oatm and o is 0.152. BERNZOMATIC MONTAN
help D Question 4 2 pts Suppose you have 12.5 g CO2(g) at 0.500 Land 355 K. Using the ideal gas law, the pressure is atm. Using the van der Waals constants for CO2 (a = 3.610 atm L/mol?, b = 0.0429 L/mol), the corrected pressure is atm. Fill in both blanks to three significant figures. Do not include units.
