The density of a solution containing `13%` by mass of sulphuric acid is `1.09 g / (mL)`. Calculate the molarity and normality of the solution.

Explanation

To solve the problem of calculating the molarity and normality of a solution containing 13% by mass of sulfuric acid (H₂SO₄) with a density of 1.09 g/mL, we can follow these steps:

### Step 1: Understand the Given Information
- The solution is 13% by mass of sulfuric acid (H₂SO₄).
- The density of the solution is 1.09 g/mL.

### Step 2: Calculate the Mass of the Solution
Assume we have 100 g of the solution. Since it is 13% by mass of H₂SO₄:
