110. Compare the pressures given by (a) the ideal gas law, (b) the van der Waals equation, and
(c) the Redlic-Kwong equation for propane at 400 K and p = 10.62 mol dm³. The van der
Waals parameters for propane are a = 9.3919 dm6 bar mol-2 and b = 0.090494 dm³ mol−1.
The Redlich-Kwong parameters are A = 183.02 dm bar mol-2 and B =
0.062723 dm³ mol-1. The experimental value is 400 bar.
Research in surface science is carried out using stainless steel ultra-high vacuum chambers with pressures as low as 10-12 torr. How many molecules are there in a 1.00 cm3 volume at this pressure and at a temperature of 300 K? For comparison, calculate the number of molecules in a 1.00 cm3 volume at atmospheric pressure and room temperature. In outer space the pressure is approximately 1.3 x 10-11 Pa and the temperature is approximately 2.7 K (determined using the blackbody radiation of the universe). How many molecules would you expect find in 1.00 cm3 of outer space?
