20. Show a correct numerical setup for calculating the molarity of the KOH * (aq) solution. Then state the calculated value of the molarity .

---- The setup

--- The molarity of KOH

Explanation:

Given

I will answer the question with the attached titration data

Required

The set and the value of the molarity of KOH

First, calculate the volume of acid (HCL) used:

Calculate the final volume of base (KOH) used:

The numerical setup is calculated using::

Where

--- the given molarity of HCL

So, we have:

Make Mb the subject

---- The correct numerical setup

The solution is then calculated as:
