If the heat of combustion of pentane is 3507 kJ `mol^(-1)` then its calorific value will be ?

Explanation

To calculate the calorific value of pentane based on its heat of combustion, follow these steps:

### Step 1: Understand the heat of combustion
The heat of combustion of pentane is given as 3507 kJ/mol. This means that when one mole of pentane (C5H12) is completely burned, it releases 3507 kJ of energy.

### Step 2: Calculate the molar mass of pentane
The molar mass of pentane (C5H12) can be calculated as follows:
- Carbon (C) has an atomic mass of approximately 12 g/mol.
