A 0.5750-kg ice cube at -12.40°C is placed inside a chamber of steam at 365.0°C. Later, you notice that the ice cube has completely melted into a puddle of water. If the chamber initially contained 6.430 moles of steam (water) molecules before the ice is added, compute the final temperature of the puddle once it settled to equilibrium. (Suppose the chamber walls are adequately flexible to allow the system to remain isobaric and consider thermal losses/gains from the chamber walls as negligible.)
