A 86.9 g sample of solid Ga at 29.8 °C is added to 257.5 g of liquid Ga at 67.6 °C in a styrofoam cup calorimeter.

The specific heat capacity of liquid gallium is 0.400 J/g°C, specific heat capacity of solid gallium is 0.371 J/g°C, and Δfus
H° = 5.59 kJ/mol. Gallium's melting point is 29.8 °C.

Now, using that information, will all of your gallium melt in the calorimeter?

If the answer is "yes", determine the final temperature in the calorimeter.
If the answer is "no", determine the grams of Ga that remain in the solid phase.
Does all the Ga melt?
Final T or grams remaining of Ga (s)
