A 5.00 mL sample of an aqueous solution of H3PO4 requires 43.2mL of 0.285M NaOH to convert all of the H3PO4 to Na2HPO4. The other product of the reaction is water. Calculate the molarity of the H3PO4 solution.

Calculate the molarity of the H3PO4 solution?This the question Answer has to be: MH3PO4 = ? mol/L but I don't know how to calculate it. Thanks for help so far

I have been going at part B of this problem for a few hours. I've completed an ice table and calculated the total number of moles based off pressure but am still unable to come up with the partial pressures. If someone could provide the steps for solving...
