What is the final temperature when 54g ice at 0oC is mixed with 200g water at 65oC
heat to melt ice + heat to raise T of melted ice to Tfinal + heat lost by warm water = 0
[mass ice x heat fusion] + [mass melted ice x specific heat H2o x (Tfinal-Tinitial)] + [mass warm water x specific heat H2O x (Tfinal-Tinitial)] = 0
Substitute and solve. The only unknown is Tf.
