Calculate the volume of 80% `H_(2)SO_(4)` by weight (density ` = 1.80 g mL^(-1)`) required to preapre 1L of 0.2 M `H_(2)SO_(4)`.

Explanation

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

### Step 1: Calculate the number of moles of H₂SO₄ needed
To find the number of moles (n) required for a 0.2 M solution in 1 L:
\[ n = M \times V = 0.2 \, \text{mol/L} \times 1 \, \text{L} = 0.2 \, \text{mol} \]
