The atmosphere of Venus consists almost entirely of CO2. Find the pressure on the surface of the planet if the gas density P = 0.07 g/cm3 and its temperature T = 750 K. Consider the gas van der Waals with critical parameters Pk = 73 atm, Vk = 94 cm3/mol and Tk = 304 K. Compare with the pressure of an ideal gas under the same conditions.
