Answer:
[ NaOH ] = 0.026 M
Explanation:
- molarity NaOH = mol NaOH / Vsln(L)
∴ Vsln = 20.46 mL = 0.02046 L
- NaOH(aq) + KHC8H4O4(aq) → KNaC8H4O4(aq) + H2O(l)
∴ Mw KH(KHC8H4O4) = 204.24 g/mol
⇒ mol KHP = 0.1082 g / 204.24 g/mol = 5.298 E-4 mol
⇒ mol NaOH = (5.298 E-4 mol KHP)( mol NaOH/mol KHP)
⇒ mol NaOH = 5.298 E-4 mol
⇒ [ NaOH ] = 5.298 E-4 mol / 0.02046 L
⇒ [ NaOH ] = 0.026 mol/L = 0.026 M
