q to raise temperature of ice from 13C to zero C (but remain as ice).
q1 = mass ice x specific heat ice x (TfinalTinitial)
q to melt ice at zero C and remain at zero C.
q2 = mass ice x heat fusion
q to raise melted ice from zero C to final T.
q3 = mass melted ice x specific heat water x (TfinalTinitial)
q to lower temperature of hot water to final T.
q4 = mass hot water x specific heat x (TfinalTinitial).
q1 + q2 + q3 + q4 = 0
Substitute each portion into q1 + q2 .... and solve for Tfinal.
