(10) A liquid mixture of n-hexane and ethanol has a measured density at 25C of 0.72g/ml. The densities of pure components at this temperature are given below. Calculate the weight fraction of n-hexane assuming ideal volume of mixing. (10) Below are vapor pressures for n-pentane and n-hexane at 44.5C. A feed with overall liquid mole fraction is 55mol%n-pentane enters an isothermal flash drum at 600mmHg and 44.5C. Write the equation that would be solved for V/F(2pts) and calculate/insert numerical values for all variables except for V/F. (8 pts). The value is not required for full
