A 500 g sample of gold heated to 971.0 deg. C is placed in a calorimeter containing 220 g of water initially at 20.0 deg. C. If no heat is lost to the surrounding environment what will the final temperature of the water be? [HINT: At the end, the sample will be in thermal equilibrium with the water.]

I used the equation ((M1C1T1) + (M2C2T2))/ ((M1C1) + (M2C2)) to get 355.397 K but it was incorrect. What am I doing wrong?

Wondering how you got Kelvin for your temperature?
you stupid
