Please don't provide handwritten solution .....

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 7 for gases better than the Ideal Gas Law does:
-nb)-NRT The van der Waals equation of state. R stands for the gas constant and for moles of gas
The parameters 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
What are the units of a?
What are the units of b
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-110.0 "C with a molar volume of
0.288 L/mol. Round your answer to 3 significant digits
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.
