In a flow process, you mix 200 g/s of benzene at 308.15 K with 300 g/s of 2-propanol at 298.15 K. Using Figure 9-3, answer the following; 

A. What is the concentration of the resulting mixture? 

B. Estimate the heat effect (added/removed) of this mixing if it is done such that the resulting tem perature is 298.15 K. 

C. If the mixing were done in an adiabatic fashion, estimate the resulting solution temperature.
