When 2 g of benzene are burnt in a bomb calorimeter, the heat produced is 83.6 kJ at 298 K. Calculate the enthalpy of combustion of benzene.

Explanation

To calculate the enthalpy of combustion of benzene when 2 g are burnt in a bomb calorimeter, we can follow these steps:

### Step 1: Identify the heat released (Q)
The heat produced during the combustion of benzene is given as 83.6 kJ. Since this is heat released, we will take it as negative:
\[ Q = -83.6 \, \text{kJ} \]

### Step 2: Calculate the number of moles (N) of benzene
To find the number of moles of benzene, we use the formula:
...
