The ionisation energy of H is 1312 kJ `mol^(- 1)`. How much energy is required to ionise 100 gram atoms of hydrogen?

Explanation

To find the energy required to ionize 100 gram atoms of hydrogen, we can follow these steps:

### Step 1: Understand the given data
The ionization energy of hydrogen (H) is given as 1312 kJ/mol. This means that to ionize one mole of hydrogen atoms, 1312 kJ of energy is required.

### Step 2: Convert gram atoms to moles
The term "gram atom" is an older term that refers to a mole. Therefore, 100 gram atoms of hydrogen is equivalent to 100 moles of hydrogen.
