Chemistry questions and answers. Use the van der Waals equation to calculate the volume, in L, occupied by a 1.00 mol sample of chlorine gas at 355 K and a pressure of 20.0 atm. For chlorine, a = 6.49 L².atm/mol² and b = 0.0562 L/mol. (Solve by successive approximations using the simplifying assumption that the value of V in the n²a/V² term ...

A) Use the van der Waals equation to calculate the pressure, in atm, of 35.62 mol of hydrogen at 91 o C in a 3.00 L container. B) Three bulbs are connected by tubing, and the tubing is evacuated. The volume of the tubing is 39.0 mL. The first bulb has a volume of 79.0 mL and contains 2.32 atm of argon, the second bulb has a volume of 250 mL and ...
The easiest one to use for REAL gases is the van der Waals equation of state (vdW EOS): P = (RT)/ (barV - b) - a/ (barV^2) where P,R, and T are known from the ideal gas law, barV -= V/n is the molar volume of the vdW gas, and a and b are van der Waals constants accounting for the attractive intermolecular forces, and the excluded volume ...

The van der Waals equation of state was designed (by Dutch physicist Johannes van der Waals) to predict the relationship between pressure p, volume V and temperature T for gases better than the Ideal Gas Law does: (p+aV2n2) (V−nb)=nRT The van der Waals equation of state. R stands for the gas constant and n for moles of gas.
