Number of moles of `Na_(2)CO_(3)` that should be dissolved in 4 litres of the solution to obtain 1 N `Na_(2)CO_(3)` solution is

Explanation

To find the number of moles of \( \text{Na}_2\text{CO}_3 \) (sodium carbonate) that should be dissolved in 4 liters of solution to obtain a 1 N (normal) solution, we can follow these steps:

### Step 1: Understand the Definition of Normality
Normality (N) is defined as the number of equivalents of solute per liter of solution. For sodium carbonate, \( \text{Na}_2\text{CO}_3 \), the normality can be calculated using the formula:

\[ \text{Normality (N)} = \frac{\text{Gram Equivalent}}{\text{Volume of solution in liters}} \]
