Calculated the energy required to excite one litre of hydrogen gas at `1atm` and `298K` to the first excited state of atomic hydorgen. The enegry for the dissociation of `H-H` bond is `436 kJ mol^(-1)`.

Explanation

To calculate the energy required to excite one liter of hydrogen gas at 1 atm and 298 K to the first excited state of atomic hydrogen, we can follow these steps:

### Step 1: Calculate the number of moles of hydrogen gas (n)
Using the ideal gas equation:
\[ PV = nRT \]

Where:
- \( P \) = Pressure = 1 atm
