A 58.8 g sample of quartz, which has a specific heat capacity of 0.730 J-gc, is put into a calorimeter (see sketch at right) that contains 150.0 g of water. The temperature of the water starts off at 18.0 °C. When the temperature of the water stops changing it's 22.8 °C. The pressure remains constant at I atm. Calculate the initial temperature of the quartz sample. Be sure your answer is rounded to 2 significant digits.
