1. What mass, in grams, of aluminum fins could 2666 J of energy heat from 15.53 ∘C to 27.68 ∘C ? Aluminum has a specific heat of 0.897 (J/g)⋅∘C.
2. What is the temperature change of the water if 206.5 g of water sat in the copper pipe, releasing 2666 J of energy to the pipe? The specific heat of water is 4.184 (J/g)⋅∘C.

Note the corrected placement of parentheses in the specific heats:
(2666 J) / (0.897 J/(g⋅∘C)) / (27.68 ∘C - 15.53 ∘C) = 244.62 = 245 g Al
(2666 J) / (4.184 J/(g⋅∘C)) / (206.5 g) = -3.086 ∘C change

I think there is a formula for this
