Answer

Answer:

C. 2.0 mL of 10.5 M H₂O₂, where H₂O₂ has a molar mass of 34 g/mol

Explanation:

Step1: Identify the concentration values

We are given the following molar - concentrations:

  • For H₂SO₄: 10 M
  • For PbSO₄: 1.0 M
  • For H₂O₂: 10.5 M
  • For NaCl: 10 M

Step2: Compare the molar - concentrations

The higher the molar - concentration of a solution, the more concentrated the solution is. Comparing the values: 1.0 M (PbSO₄) < 10 M (H₂SO₄ and NaCl) < 10.5 M (H₂O₂)

So the most concentrated solution is 2.0 mL of 10.5 M H₂O₂.
