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.

What are the units of $a?$

What are the units of $b?$

For carbon dioxide the numerical value of $a$ is $3\mathrm{.}592$ and the numerical value of $b$ is $0\mathrm{.}0429.$

Use the van der Waals equation to calculate the pressure of a sample of carbon dioxide at $95\mathrm{.}0C$ with a molar volume of $5\mathrm{.}53$ 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.
