**DrBob222**, Tuesday, May 13, 2014 at 8:16pmTo melt ice requires q1 = mass ice x heat fusion.

To raise T of melted ice at zero C to Tfinal requires q2 = mass melted ice x specific heat liquid H2O x (Tfinal-Tinitial)

To cool the water from 75C to Tfinal requires q3 = mass liquid water x specific heat x (Tfinal-Tinitial).

Just substitute q1 + q2 + q3 = 0 and solve for Tf.
