Answer:
The concentration of the standard NaOH solution is 0.094 moles/L.
Explanation:
In the titration, the equivalence point is defined as the point where the moles of NaOH (the titrant) and KHP (the analyte) are equal:
moles of NaOH = moles of KHP
![[NaOH]xV_{NaOH} = moles of KHP](https://tex.z-dn.net/?f=%5BNaOH%5DxV_%7BNaOH%7D%20%3D%20moles%20of%20KHP)
![[NaOH] = \frac{moles of KHP}{V_{NaOH}}](https://tex.z-dn.net/?f=%5BNaOH%5D%20%3D%20%5Cfrac%7Bmoles%20of%20KHP%7D%7BV_%7BNaOH%7D%7D)
The
is 40.82mL = 0.04082L and the moles of KHP are

Replacing at the first equation:
![[NaOH] = \frac{3.827x10^{-3}moles}{0.04082L} = 0.094 moles/L](https://tex.z-dn.net/?f=%5BNaOH%5D%20%3D%20%5Cfrac%7B3.827x10%5E%7B-3%7Dmoles%7D%7B0.04082L%7D%20%3D%200.094%20moles%2FL)
