Is there some problem with you finding or understanding the solution?

Is there some difficulty with typing your subject (chemistry) in the subject line?

What do they teach in Tennessee?

To calculate the heat absorbed by the calorimeter, you need to use the formula:

Heat Absorbed = (Temperature Change) x (Calorimeter Constant)

In this case, the temperature change is given as 12 °C and the calorimeter constant (heat capacity) is given as 3.3 J/K.

First, you need to convert the temperature change from °C to Kelvin (K), as the temperature change needs to be in Kelvin for the calculations. The Kelvin temperature scale is the same size as the Celsius scale, but it starts at absolute zero (−273.15 °C). To convert from °C to K, simply add 273.15 to the temperature in Celsius.

Temperature Change in Kelvin = Temperature Change in Celsius + 273.15

Temperature Change in Kelvin = 12 °C + 273.15
Temperature Change in Kelvin = 285.15 K

Now, you can calculate the heat absorbed:

Heat Absorbed = Temperature Change x Calorimeter Constant

Heat Absorbed = 285.15 K x 3.3 J/K
Heat Absorbed ≈ 941.50 J

Therefore, the amount of heat absorbed by the calorimeter is approximately 941.50 Joules.
