Final answer:

The calorimetry experiment yields 92 calories as the amount of energy released by the combustion of the chip. This is calculated using the mass of water, the temperature change, and the specific heat capacity of water.

Step-by-step explanation:

To calculate the amount of energy in calories that the chip released during the combustion in the calorimetry experiment, we can use the formula:

Q = mcΔT

Where:

  • Q is the heat energy in calories,
  • m is the mass of the water in grams,
  • c is the specific heat capacity of water (1 cal/g°C), and
  • ΔT is the change in temperature (°C).

Given the mass m of water is 20.0 grams and the change in temperature ΔT is 27.1°C - 22.5°C = 4.6°C, the equation becomes:

Q = 20.0g * 1 cal/g°C * 4.6°C = 92 calories

Thus, the number of calories in the chip is 92 calories.
