<u>Answer:</u> The number of moles of weak acid is
moles.
<u>Explanation:</u>
To calculate the moles of KOH, we use the equation:
![\text{Molarity of the solution}=\frac{\text{Moles of solute}}\text{Volume of solution (in L)}}](https://tex.z-dn.net/?f=%5Ctext%7BMolarity%20of%20the%20solution%7D%3D%5Cfrac%7B%5Ctext%7BMoles%20of%20solute%7D%7D%5Ctext%7BVolume%20of%20solution%20%28in%20L%29%7D%7D)
We are given:
Volume of solution = 43.81 mL = 0.04381 L (Conversion factor: 1L = 1000 mL)
Molarity of the solution = 0.0969 moles/ L
Putting values in above equation, we get:
![0.0969mol/L=\frac{\text{Moles of KOH}}{0.04381}\\\\\text{Moles of KOH}=4.24\times 10^{-3}mol](https://tex.z-dn.net/?f=0.0969mol%2FL%3D%5Cfrac%7B%5Ctext%7BMoles%20of%20KOH%7D%7D%7B0.04381%7D%5C%5C%5C%5C%5Ctext%7BMoles%20of%20KOH%7D%3D4.24%5Ctimes%2010%5E%7B-3%7Dmol)
The chemical reaction of weak monoprotic acid and KOH follows the equation:
![HA+KOH\rightarrow KA+H_2O](https://tex.z-dn.net/?f=HA%2BKOH%5Crightarrow%20KA%2BH_2O)
By Stoichiometry of the reaction:
1 mole of KOH reacts with 1 mole of weak monoprotic acid.
So,
of KOH will react with =
of weak monoprotic acid.
Hence, the number of moles of weak acid is
moles.
