Which of the following amounts of solute,dissolved in 1.0 kg of water,creates a solution with the highest freezing temperature? (assuming ideal behavior) A)0.0015 mol of sucrose,C₁₂H₂₂O₁₁ B)0.0015 mol of H₂SO₃ C)0.0030 mol of ethanol,C₂H₅OH D)0.0030 mol of methanol,CH₃OH E)0.0015 mol of sulfuric acid,H₂SO₄
