WebSep 14, 2024 · The molarity of the acid is given, so the number of moles titrated can be calculated: 0.050 L × 6 mol/L = 0.3 moles of strong acid added thus far. If 0.3 < initial moles of base, the equivalence point has not yet been reached. I f 0.3 = initial moles of base, the titration is at the equivalence point.
