Final answer:
The heat transferred during the combustion of the 1.500 g sample of toluene in a bomb calorimeter with a 45.06 kJ/°C heat capacity was 64.436 kJ.
Step-by-step explanation:
To find the amount of heat transferred during the combustion of toluene in a bomb calorimeter, we use the heat capacity of the calorimeter and the change in temperature.
The combustion caused the temperature to rise from 25.00 to 26.43 degrees Celsius, an increase of 1.43 degrees.
The bomb calorimeter has a heat capacity of 45.06 kJ/°C, and the formula to calculate the heat (q) is:
q = heat capacity × ∆T
where q is the heat transferred and ∆T is the change in temperature.
Calculating the value:
q = 45.06 kJ/°C × 1.43 °C
= 64.436 kJ
This means 64.436 kJ was the amount of heat released during the combustion of the 1.500 g sample of toluene.
