A 54.3 g sample of quartz is put into a calorimeter (see sketch at right) that contains 250.0 g of water. The quartz sample starts off at 87.5 °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 specific heat capacity of quartz according to this experiment. Be sure your answer is rounded to 2 significant digits.

**Calorimetry Experiment: Determining Specific Heat Capacity of Quartz**

A 54.3 g sample of quartz is placed into a calorimeter, as illustrated in the adjacent sketch. The calorimeter contains 250.0 g of water. Initially, the quartz sample is at a temperature of 87.5 °C, while the water starts at 18.0 °C. When equilibrium is reached, the water's final temperature is 20.6 °C. The pressure remains constant at 1 atm throughout the experiment.

**Objective:**
Calculate the specific heat capacity of quartz based on this experimental setup. Ensure the answer is rounded to two significant digits.

**Diagram Explanation:**
The right side of the image shows a labeled diagram of a calorimeter. It includes:
- A thermometer to measure the temperature.
- An insulated container to minimize heat loss.
- Water in which the quartz sample is submerged.

Be sure to express the specific heat capacity in J/g·°C. Use the formula and insert values accordingly to compute the result.
