Problem: A 0.5530-kg ice cube at -12.40oC is placed inside a chamber of steam at 365.0oC. Later, you noticed that the ice cube has completely melted into a puddle of water. If the chamber initially contained 6.670 moles of steam (water) molecules before the ice is added, calculate the final temperature of the puddle once it settled to equilibrium. (Assume the chamber walls are sufficiently flexible to allow the system to remain isobaric and consider thermal losses/gains from the chamber walls as negligible.)
