What is the molarity of a solution prepared by diluting 75 mL of 2.35 M Na₂SO₄ solution to a final volume of 250 mL?

Question

Quizplus · Accepted Answer

The formula for dilution is:

M1V1 = M2V2

Where M1 and V1 are the initial concentration and volume of the solution, and M2 and V2 are the final concentration and volume of the solution.

Substituting the given values, we get:

2.35 M x 75 mL = M2 x 250 mL
M2 = (2.35 M x 75 mL) / 250 mL
M2 = 0.705 M

Therefore, the molarity of the final solution is 0.705 M, which corresponds to choice C.
