5) An insulated container holds 90.0 g of water (H2O, M = 18.0 g/mol) at T = 50.0 ºC. A 10.0 g ice cube, at T = 0.0 ºC, is added to the container, and the system is allowed to come to equilibrium.
a) Find the value for Tf, the final temperature of the water in the insulated container.
b) Find the value for ∆S, the entropy change for the above process.
NOTE: Cp,m(H2O(L)) = 75.29 J/mol.K, and ∆Hºfus(H2O) = 6008. J/mol.
