Question

What volume in milliliters of H20 you need during preparation of 100 milliliters of 14.00 M H2SO4 solution starting with bottle of 17.5 M H2SO4? (Round your answer to closest integer)

Answer 1

20 mL

Step-by-step explanation:

We can determine the required volume of the concentrated (17.5 M) H₂SO₄ solution by using the C₁V₁=C₂V₂ formula:

• 17.5 M * V₁ = 14.00 M* 100 mL

• V₁ = 80 mL

As out of the 100 mL of the final solution, 80 mL are from the concentrated H₂SO₄ solution, the remaining 20 mL are of water (H₂O).
