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

Explanation

To understand the difference between 0.50 m Na₂CO₃ and 0.50 M Na₂CO₃, we need to define molality (m) and molarity (M) and see how they are calculated.

### Step-by-Step Solution:

1. **Define Molarity (M)**:
- Molarity is defined as the number of moles of solute per liter of solution.
- For 0.50 M Na₂CO₃, it means there are 0.50 moles of Na₂CO₃ dissolved in 1 liter of solution.
