The `Ka` X-ray of molybdenum has wavelength 71 pm. If the energy of a molybdenum atom with a K electron knocked out is 23.32 keV, what will be the energy of this atom when an L electron is knocked out?

Explanation

To solve the problem, we need to find the energy of a molybdenum atom when an L electron is knocked out, given that the energy of the atom with a K electron knocked out is 23.32 keV.

### Step-by-Step Solution:

1. **Understanding the Energy Levels**:
- In an atom, electrons occupy different energy levels (K, L, M, etc.). The K level is the closest to the nucleus, while the L level is the next one. When an electron is knocked out from these levels, the energy of the atom changes.

2. **Given Information**:
