A storage battery contains a solution of `H_(2)SO_(4) 38%` by weight. At this concentration, the Vant't Hoff factor is `2.50`. At what temperature will the battery contents freeze? `(K_(f)=1.86^(@) mol^(-1) kg)`

Explanation

To solve the problem of determining the freezing point of a storage battery solution containing 38% H₂SO₄ by weight, we will follow these steps:

### Step 1: Determine the mass of the solute and solvent
Given that the solution is 38% H₂SO₄ by weight, we can assume:
- Mass of H₂SO₄ (solute), W₂ = 38 g
- Mass of the solution = 100 g
- Therefore, mass of the solvent (water), W₁ = 100 g - 38 g = 62 g
