n moles of gas are in a V L tank at T °C . Assume the van der Waals equation approximates the behavior of O2
under these conditions, and calculate the difference* in pressure between oxygen and an ideal gas in these conditions.
The van der Waals constants for oxygen are a = 1.382L2 ⋅atm/mol2 and b = 0.03186 L/mol.
V = 4 LL
T = 24.3 °C
