On the plot below your are given measurements and a best fit of the compressibility factor of a gas as a function of the molar volume at a temperature of 200 K, 0.998 0.996 ..............I slope 0.1 0.994. 0.992 !.................4. ......a 0.99 0.02 0.04 0.06 0.08 0.1 1/ (mol/dms) Given the slope of the fit, indicated on the plot, at a temperature of 200 K what is the pressure of this gas at a fixed molar volume of V 0.2 dm mol? Assume that all virial coefficients beyond the second CB are negligible.
