Compute the difference in masses of one mole each of aluminium atoms and one mole of its ions? (Mass of electron is `9.1 xx 10^(-28)` g). Which one is heavier?

Explanation

To compute the difference in masses of one mole of aluminum atoms and one mole of aluminum ions, we can follow these steps:

### Step 1: Understand the ionization of aluminum
Aluminum (Al) has an atomic number of 13, which means it has 13 electrons in its neutral state. When aluminum forms an ion, it typically loses 3 electrons to become Al³⁺.

### Step 2: Calculate the mass of electrons lost
Since one mole of aluminum atoms loses 3 moles of electrons to form one mole of aluminum ions, we need to calculate the mass of these 3 moles of electrons.
