How are `0.50 mol Na_(2)CO_(3)` and `0.50 M Na_(2)CO_(3)` different?

Explanation

To understand the difference between `0.50 mol Na₂CO₃` and `0.50 M Na₂CO₃`, we can break down the concepts of moles and molarity step by step.

### Step 1: Understand Moles
- **Definition**: A mole is a unit that measures the amount of a substance. One mole contains \(6.022 \times 10^{23}\) entities (atoms, molecules, etc.), known as Avogadro's number.
- **Example**: `0.50 mol Na₂CO₃` means we have \(0.50\) moles of sodium carbonate (Na₂CO₃). This is equivalent to:
\[ 0.50 \, \text{mol} \times 6.022 \times 10^{23} \, \text{molecules/mol} \approx 3.01 \times 10^{23} \, \text{molecules of Na₂CO₃} \]
