A 28.00 mL sample of an unknown H3PO4 solution is titrated with a 0.130 M NaOH solution. The equivalence point is reached when 26.13 mL of NaOH solution is added.
The neutralization reaction is
What is the concentration of the unknown H3PO4 solution?

(0.130 M NaOH) x (26.13 mL) x (1 mol H3PO4 / 3 mol NaOH) / (28.00 mL) =
0.0404 M H3PO4
