Final answer:
The heat produced by the combustion of the benzene sample is 70.429 J.
Step-by-step explanation:
To calculate the amount of heat produced by the combustion of the benzene sample, we can use the equation q = (m_water x Cs_water x ΔT_water) + (m_bomb x Cs_bomb x ΔT_bomb), where q is the heat produced, m_water is the mass of water, Cs_water is the heat capacity of water, ΔT_water is the change in temperature of water, m_bomb is the mass of the bomb calorimeter, Cs_bomb is the heat capacity of the bomb calorimeter, and ΔT_bomb is the change in temperature of the bomb calorimeter.
Plugging in the given values:
q = (0.925 kg x 4.18 J/(g·°C) x 8.39 °C) + (0.963 g x 784 J/°C x 8.39 °C)
q = 63.933 J + 6.496 J
q = 70.429 J
Therefore, the heat produced by the combustion of the benzene sample is 70.429 J.
