Assuming non-ideal behavior, a 2. 0 mol sample of co₂ in a 7. 30 l container at 200. 0 k has a pressure of 4. 50 atm. If a = 3. 59 l²･atm/mol² and b = 0. 0427 l/mol for co₂, according to the van der waals equation what is the difference in pressure (in atm) between ideal and nonideal conditions for co₂?.
