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 bar and a temperature of 355.0 K. (Hint: One way to solve the van der Waals equation for V is to use successive approximations. Use the ideal gas law to get a preliminary estimate for V ITS 500BAR use bar please not ATM
Enter your answer in the provided box. Because the van der Waals constant b is the excluded volume per mole of a gas, we can use the value of b to estimate the radius of a molecule or an atom. Consider a gas that consists of molecules, for which the van der Waals constant b is 0.0295 L/mol. Estimate the molecular radius in picometers. Assume that the molecules are spherical.
