A 25 ml mixture of HCl-H3PO4 was diluted with 75ml with dH2O, total volume 100ml, and then 25 ml of that was removed and added with 75 ml of dH2O. This mixture was then titrated with 0.1M NaOH, attached is data that was found. What are the molarities of the HCl and H3PO4 in the original solution?

First equivalence point:
HCl + NaOH -> H2O + NaCl
H3PO4 + NaOH -> NaH2PO4 +H2O

Second equivalence point:
NaH2PO4 + NaOH -> Na2HPO4 +H2O
