GASES LIGOS, AND SOLIDS Using the van der Waals equation of state hun web The van der Waals equation of state was designed (by Dutch physicist Johannes van der Waals) to predict the relationship between pressure p, volume and temperature T for gases better than the Ideal Gas Law does: (V-nb) - RT The van der Waals equation of state. R stands for the gas constant and for moles of gas The parameters a and b must be determined for each gas from experimental data Use the van der Waals equation to answer the questions in the table below. L What are the units of a? DO LI X 5 What are the units of 57 atm For argon the numerical value of a is 1.337 and the numerical value of bis 0.0320 Use the van der Waals equation to calculate the pressure of a sample of argon at - 105.0 C with a molar volume of 3.65 L/mol Round your answer to the correct number of significant digits. Use the Ideal Gas Law to calculate the pressure of the same sample under the same conditions. Round your answer to the correct number of significant digits. 3021 MG Am Check Explanation
