<u>Answer:</u> The molarity of NaOH solution is 0.273 M.
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
Given mass of KHP = 1.794 g
Molar mass of KHP = 204.2 g/mol
Putting values in above equation, we get:
The chemical reaction for the reaction of KHP and NaOH follows
By Stoichiometry of the reaction:
1 mole of KHP reacts with 1 mole of NaOH.
So, 0.0088 moles of KHP will react with = of NaOH
To calculate the molarity of NaOH, we use the equation:
We are given:
Moles of NaOH = 0.0088 moles
Volume of solution = [32.47 - 0.23] mL = 32.24 mL = 0.03224 L (Conversion factor: 1 L = 1000 mL)
Putting values in above equation, we get:
Hence, the molarity of NaOH solution is 0.273 M.
