The van der Waals equation of state was designed (by Dutch physicist Johannes van der Waals) to predict the relationship between pressure p, volume V and temperature T for gases better than the Ideal Gas Law does:=+pan2V2-VnbnRT

The van der Waals equation of state. R stands for the gas constant and n 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.

a. For water the numerical value of a is5.464 and the numerical value of b is0.0305. Use the van der Waals equation to calculate the pressure of a sample of water at 425.0°C with a molar volume of 0.183/L mol. Round your answer to 3 significant digits. Answer in atm

b. Use the Ideal Gas Law to calculate the pressure of the same sample under the same conditions. Round this answer to 3 significant digits also. Answer in atm
