Perform the same computation as in Sec. 8.1, but for ethyl alcohol (a = 12.02 and b = 0.08407) at a temperature of 400 K and p of 2.5 atm. Compare your result with the ideal gas law. If possible, use your computer software to determine the molal volume. Otherwise, use any of the numerical methods discussed in Chaps.5 and 6 to perform the computation. Justify your choice of technique.
