clear hand writing and not a lot of details please.

Figure 19-22 9-23. A mass of 500 lb of 40 wt% sulfuric acid solution at 140F is diluted with 200 lb of pure water at 100F. What is the concentration of the resulting solution? What is the heat effect (liberated or absorbed) of this mixing (report an extensive number) if the mixing is done such that the resulting solution is at 100F? If the mixing was done adiabatically, what would be the resulting solution temperature? Use Figure P9-22
