160 grams of ethanol at 30 degrees Celsius is mixed with 250 grams of ethanol at 77 degrees Celsius at constant atmospheric pressure in a thermally insulated vessel. What is the Delta S sys for the process? Specific heat capacity for ethanol is 2.42 J/g K. So I got up to the part of getting what t should equal 331.8085. I just don't know how to do the rest of it after Delta S sys because the teacher didn't teach us. Help?
