A 0.66300.6630 kg ice cube at −12.40−12.40 °C is placed inside a rigid, thermally isolated chamber containing steam at 365.0365.0 °C. Later, you notice that the ice cube has completely melted into a puddle of water. The specific heats of ice, water, and steam are ?ice=2093 J/(kg·∘C),cice=2093 J/(kg·∘C), ?water=4186 J/(kg·∘C),cwater=4186 J/(kg·∘C), and ?steam=2009 J/(kg·∘C),csteam=2009 J/(kg·∘C), respectively.

If the chamber initially contained 6.1906.190 moles of steam (water) molecules before the ice was added, calculate the final temperature ?fTf of the puddle once it settled to equilibrium.
