Question: You have 100g of water at 30C to which you add 50g of ice at 0C. Calculate the entropy change for the process. For this problem I solved for the final temperature, Tf, and got that it is equal to 17.333 C = 290.483 K I have to solve for the change in entropy, though. How would I go about doing this? I was going to either use the formula: Delta S = n*Cp(molar)*ln(Tf/Ti) with n = (150/18.016 mols...
