What is the molarity of a NaOH solution if 28.2 mL of a 0.355 M H2SO4 solution is required to neutralize a 25.0-mL sample of the NaOH solution?A) 0.801B) 0.315C) 0.629D) 125E) 0.400

A) 0.801

Explanation:

The reaction that takes place is:

First we calculate the H₂SO₄ moles that reacted:

Now we convert H₂SO₄ moles to NaOH moles:

Finally we calculate the molarity of the NaOH solution:

So the answer is option A.

the answer would be a
