Find the constants (a and b) for O2 in Table 5.7. Use the Van der Waals equation to determine the pressure of 1.000 mole of O2 if the gas occupies 22.50 liters at 27.00 oC. First, find the values for each of the two terms in the equation, then find the difference. Show all units in the equation, and use correct significant digits in your result.
I put the number in the formula of P=nRT/v-(nb) - an^2/V^2 after calculating the numbers I got 1.001 atm would this be correct?

When you post a problem like this it does little good unless you post the constants you are using too. We are likely to use the wrong set in our book and the answer we come up may not agree with yours but both could be right with the constants we've used. As it turns out my book doesn't list any constants. I did go to the web and found a van der Waals calculator that gave me the number 1.093 atm for the numbers. I didn't go through to find the correct number of s.f.
