1.26 g of hydrated oxalic acid was dissolved in water to prepare 250 ml of solution. Calculate molarity of solution

Explanation

To calculate the molarity of the hydrated oxalic acid solution, we will follow these steps:

### Step 1: Understand the concept of molarity
Molarity (M) is defined as the number of moles of solute per liter of solution. The formula for molarity is:
\[ \text{Molarity (M)} = \frac{\text{Number of moles of solute}}{\text{Volume of solution in liters}} \]

### Step 2: Determine the formula of hydrated oxalic acid
The formula for hydrated oxalic acid is \( \text{C}_2\text{H}_2\text{O}_4 \cdot 2\text{H}_2\text{O} \). This means it contains 2 carbon atoms, 2 hydrogen atoms from oxalic acid, and 4 oxygen atoms from oxalic acid plus 2 water molecules.
