(pies or-nd) (V-nb)=nRT
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.
D.
What are the units of a?
0
x ola
0
What are the units of b?
5

For carbon dioxide the numerical value of a is 3.592 and the
numerical value of bis 0.0429
atm
Use the van der Waals equation to calculate the pressure of a
sample of carbon dioxide at 45.0 °C with a molar volume of
0.257 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.
