An ice cube weighing 22.7 g at a temperature of 0.0°C is added to 125 mL of water at 27.1°C in an insulated container. What will be the final temperature after the ice has melted?
heat added to melt ice + heat gained by water from ice + heat lost by 125 mL H2O = 0
(22.7g ice x heat fusion) + (22.7 g H2O x 4.184 x (Tfinal - Tinitial) + (125 x 4.184 x (Tfinal-Tinitial) = 0
I get approx 11 degrees C.
Solve for Tfinal.
