During a titration, 50.0ml of 0.2 NaOH were required to neutralize 50.0ml of H3PO4. What’s the concentration of the H3PO4 solution?

The titration of 80.0 mL of an unknown concentration of H₃PO₄ solution requires 126 mL of 0.218 M KOH solution. What is the concentration of the H₃PO₄ solution (in M)?

1- How would you prepare 1 L of HCl 0.1 M from a HCl 12 M solution?2- What is the concentration of 50 mL of a solution of NaOH if 25 mL of HCl 0.1M areneeded to reach the equivalence point during a titration?3- What volume of 0.812 M HCl is required to titrate 1.45 g of NaOH to the equivalencepoint?4- What volume of 0.955 M HCl is required to titrate 2.152 g of Na2CO3 to theequivalence point?5- What is the concentration of HCl if 41.9 mLare required to neutralize 2.152 gNa2CO3?

It was found that 19.60 mL of NaOH solution were required to neutralize 10.00 mL of HCl. If the concentration of the base solution was 0.1051 M, calculate the concentration of the acid solution.
