A 52.6 g sample of aluminum, which has a specific heat capacity of 0.897 J x g ^-1 x C^-1, is put into a calorimeter that contains 100.0 g of water. The temperature of the water starts off at 18. C . When the temperature of the water stops changing it's 26.1 C. The pressure remains constant at 1 atm. Calculate the initial temperature of the aluminum sample. Be sure your answer is rounded to 2 significant digits.
