In this experiment, we initially assume that the heat capacity of the calorimeter device (i.e., the coffee cups and thermometer) is negligible relative to that of its contents. Employing this assumption, what is the approximate heat capacity of a calorimeter containing 99.3 g of water?

Final answer:

The approximate heat capacity of a calorimeter containing 99.3 g of water is approximately 414.174 J/°C.

Explanation:

To calculate the approximate heat capacity of a calorimeter containing 99.3 g of water, we need to consider the specific heat capacity of water and the mass of water in the calorimeter.

The specific heat capacity of water is approximately 4.18 J/g°C. This means that it takes 4.18 Joules of energy to raise the temperature of 1 gram of water by 1 degree Celsius.

Given that we have 99.3 g of water in the calorimeter, we can calculate the approximate heat capacity as follows:

  1. Heat capacity = mass of water * specific heat capacity of water
  2. Heat capacity = 99.3 g * 4.18 J/g°C
  3. Heat capacity ≈ 414.174 J/°C

Therefore, the approximate heat capacity of the calorimeter containing 99.3 g of water is approximately 414.174 J/°C.
