For 1.00 mol of Cl₂ in a volume of 2.50 L, calculate the difference in the energy between U_ideal and U_vw. What is the percentage difference when compared with U_ideal?

2. (a) Using the ideal gas equation, calculate the volume of 1 mol of a gas at a temperature of 25 °C and a pressure of 1 atm. This volume is called the Avogadro volume. (b) The atmosphere of Venus is 96.5% CO₂(g). The surface temperature is about 730 K and the pressure is about 90 atm. Using the ideal gas equation, calculate the volume of 1 mol of CO₂(g) under these conditions (Avogadro volume on Venus). (c) Use Maple/Mathematica and the van der Waals equation to obtain the Avogadro volume on Venus and compare it (fi nd the percentage difference) with the result obtained using the ideal gas equation.
