You want to calculate the density of a gas at 192 °C and 9000 kPa. You know that the gas has critical temperature of 37 °C, critical pressure of 4500 kPa, and molecular weight of 30.0. Calculate the density in kg/m3 using (a) the ideal gas equation of state and (b) the compressibility factor equation of state in conjunction with the law of corresponding states.
