<u>Answer:</u> The concentration of KOH solution is 0.103 M.
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
Given mass of KHP = 0.4877 g
Molar mass of KHP = 204.22 g/mol
Putting values in equation 1, we get:
The chemical reaction for the reaction of KHP with KOH follows:
By Stoichiometry of the reaction:
1 mole of KHP reacts with 1 mole of KOH.
So, 0.0024 moles of KHP will react with = of KOH.
- To calculate the molarity of KOH, we use the equation:
We are given:
Moles of KOH = 0.0024 moles
Volume of solution = 23.22 mL = 0.02322L (Conversion factor: 1L = 1000 mL)
Putting values in above equation, we get:
Hence, the molarity of KOH solution is 0.103 M.
