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` (molality) and 0.50 M `Na₂CO₃` (molarity), we need to define both terms and analyze their meanings in the context of solutions.

### Step-by-Step Solution:

1. **Definition of Molarity (M)**:
- Molarity (M) 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 sodium carbonate dissolved in 1 liter of total solution.
