please help with 1 and 2 this is for chemical engineering principles 2. thank you!!

1. (5pt) You are about to dilute 15mol of 100% sulfuric acid (H2SO4) with enough water to produce a 40mol% aqueous solution. The acid and water are initially at 25C. a. How much heat [kJ] would have to be removed to keep the final solution at 25C ? b. Suppose the flask has a mass of 220g and that the heat capacity of the flask and its contents is 3.30J/gC. If the flask is sufficiently insulated to be considered adiabatic, what will the final solution temperature be in C ? 2. (5pt) Humid air is enclosed in a 2.00 -liter flask at 40C. The flask is slowly cooled. When the temperature reaches 20C, drops of moisture become visible on the flask wall. Although the pressure in the flask changes when the temperature drops, it remains close enough to 1atm for the psychrometric chart to provide a close representation of the behavior of the system throughout the process. Use the psychrometric chart to solve the following problems. a. What were the relative humidity, absolute humidity, and wet-bulb temperature of the air at 40C ? b. Calculate the mass of water in the flask. c. Calculate the enthalpy change in joules undergone by the air going from 40C to 20C d. Write an energy balance for this closed-system process, taking the wet air in the flask as the system and use it to calculate the heat in joules that must be transferred from the air to accomplish the cooling
