A Lab Assistant Pours 330 G of Water at 45°C $900 \mathrm {~J} / \mathrm { kg } \cdot \mathrm { K } ,$

A lab assistant pours 330 g of water at 45°C into an 855-g aluminum container that is at an initial temperature of 10°C.The specific heat of aluminum is $900 \mathrm {~J} / \mathrm { kg } \cdot \mathrm { K } ,$ and that of water is 4186 J/kg ∙ K.What is the final temperature of the system,assuming no thermal energy is exchanged with the surroundings?

A) 28°C
B) 32°C
C) 31°C
D) 33°C
E) 35°C
