The difference in the mass of 100 moles of each of sodium atoms and sodium ions is `5.48002` g. Compute the mass of an electron.

Explanation

To find the mass of an electron based on the given difference in mass between sodium atoms and sodium ions, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Problem**:
- We know that the difference in mass between 100 moles of sodium atoms (Na) and 100 moles of sodium ions (Na⁺) is given as 5.48002 grams.
- When sodium loses an electron to become a sodium ion, that electron has mass.
