solve 3 and 4 please ASAP

Problem 3 (10 points) Sulfolane is an organic solvent used for extracting aromatic hydrocarbons from hydrocarbon mixtures. 100 kg/hr of a solution of 30k toluene in heptane is mixed a stream of pure sulfolane. The resulting mixture is allowed to separate, and the sulfolane-rich phase has 40s toluene in it. a) What is the composition of the two phases exiting the process? (4 pts) b) What is the required mass flow rate of sulfoline? ( 5pt ) c) What is the percentage of toluene that is "transferred" from the heptane to the sulfolane-rich phace? (Ipt) Problem 4(10 points) Water at 60 bar and an unknown temperature enten a turbine at a rate of 12kg/. The water exits the turbine at. I bar as a mixture with quality 0.95 . The turbine generites 13.7MW of power, while 700kW are lost as heac. Determine the temperature and state of the water enteting the turbine
