Question

2dm³ of 4M H₂SO4 is mixed with 3 dm³ water. What is the molarityoffinal solution

Answer 1

Answer:

1.6 M

Explanation:

Here a specific H₂SO₄ solution is diluted since it is mixed with water.

According to dilution principle ,

M₁V₁ = M₂V₂

Let 1 denote initial solution and 2 the final solution

M₂= M₁V₁/V₂

    = 4 x 2 / (2+3)

    = 8/5 M

    = 1.6 M
