Calculate the number of oxialic acid molecules in `100 mL` of `0.02 N` oxialic acid

Explanation

To calculate the number of oxalic acid molecules in 100 mL of 0.02 N oxalic acid, we can follow these steps:

### Step 1: Understand the relationship between normality and molarity
Normality (N) is related to molarity (M) through the formula:
\[ \text{Molarity (M)} = \frac{\text{Normality (N)}}{\text{n factor}} \]

### Step 2: Determine the n factor for oxalic acid
Oxalic acid (C₂H₂O₄) can donate two protons (H⁺ ions) in a reaction, so its n factor is 2.
