Calculate the number of moles of iodine in a sample containing `1.0 xx 10^22` molecules.

Explanation

To calculate the number of moles of iodine in a sample containing \(1.0 \times 10^{22}\) molecules, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Avogadro's Number**:
Avogadro's number (\(N_A\)) is the number of molecules in one mole of a substance. It is approximately \(6.022 \times 10^{23}\) molecules/mole.

2. **Set Up the Relationship**:
