It requires `2.378xx10^(7)`J energy to ionise a certain amount of helium gas. If ionisation energy of helium is 2378.0 kJ/mol, calculate the amount of helium gas ionised.

Explanation

To solve the problem of calculating the amount of helium gas ionized given the energy required and the ionization energy, we can follow these steps:

### Step 1: Understand the Given Data
We know:
- The energy required to ionize helium gas: \( E = 2.378 \times 10^7 \, \text{J} \)
- The ionization energy of helium: \( \text{IE} = 2378.0 \, \text{kJ/mol} \)

### Step 2: Convert Ionization Energy to Joules
