0.1092 g of a dibasic acid is exactly neutralized by `21cm^(3)` of 0.1N NaOH. Calculate the molecular mass of the acid.

Explanation

To calculate the molecular mass of the dibasic acid, we can follow these steps:

### Step 1: Understand the given data
- Mass of the dibasic acid = 0.1092 g
- Volume of NaOH = 21 cm³ = 21 mL
- Normality of NaOH = 0.1 N

### Step 2: Calculate the number of equivalents of NaOH used
