The answer to States of Matter
How reliable is the perfect gas law in comparison with the van der Waals equation? Calculate the difference in pressure of 10.00g of CO2 confined to a volume of 100cm3 at 25 degrees Celsius between treating it as a perfect gas and a van der Waals gas. Parameters for CO2 a=3.61 atm dm6 mol-2 b= 4.29 10-2 dm3 mol-1
