Use the van der Waals equation and the ideal gas equation to calculate the volume of 1.000 mol of neon at a pressure of 500.0 atm and a temperature of 355.0 K.
The Van der Waals equation, also known as the Van der Waals equation of state, is an equation of state used in chemistry and thermodynamics that extends the ideal gas law to take into account the effects of molecular interaction as well as the finite size of the molecules in a gas.
We may build a new equation that better reflects real gas behavior by modifying the ideal gas law to include corrections for interparticle attractions and particle volumes. The van der Waals equation can be used to determine a gas's properties under less-than-ideal circumstances.

Answer:
Area of the shaded region = 329.7cm
Explanation:
Area of circle = π r2
Area of smaller circle with radius of 4 cm = 3.14 * 4 * 4 = 50.24cm
Area of bigger circle with radius of 11 cm = 3.14 * 11 * 11 = 379.94cm
To calculate the area of shaded region,
Area of the shaded region = bigger region - smaller region
39.7 - 50.24 = 329.7cm
Area of the shaded region =
