1 A sample of quartz, which has a specific heat capacity of 0.730 J·g *.°C ', is put into a calorimeter (see sketch at right) that contains 250.0 g of water. The quartz sample starts off at 88.9 °C and the temperature of the water starts off at 18.0 °C. When the temperature of the water stops changing it's 20.6 °C. The pressure remains constant at 1 atm. Calculate the mass of the quartz sample. Be sure your answer is rounded to 2 significant digits.
