Calculate the volume of 80% `H_2SO_4` by weight `(density =1.80 g mL^(−1) )`required to prepare 1 L of 0.2M `H_2SO_4` .

Explanation

To solve the problem of calculating the volume of 80% H₂SO₄ by weight required to prepare 1 L of 0.2 M H₂SO₄, we can follow these steps:

### Step 1: Calculate the number of moles of H₂SO₄ required
To prepare 1 L of a 0.2 M solution, we can use the formula:
\[ \text{Moles of solute} = \text{Molarity} \times \text{Volume (in liters)} \]
Given:
