The question is incomplete, here is the complete question.

An aqueous solution at 25°C has a concentration of . Calculate the concentration. Be sure your answer has the correct number of significant digits.

The hydronium ion concentration of the solution is

Explanation:

To calculate pOH of the solution, we use the equation:

We are given:

Putting values in above equation, we get:

To calculate the hydronium ion concentration, we first calculate pH of the solution, which is:

pH + pOH = 14

pH + 7.72 = 14

pH = 14 - 7.72 = 6.28

To calculate the hydronium ion concentration of the solution, we use the equation:

We are given:

pH = 6.28

Putting values in above equation, we get:

Hence, the hydronium ion concentration of the solution is
