35 mL of a 3.2 M solution of hydrochloride acid is mixed with 30 mL if a 1.75 M solution of sodium phosphate to produce phosphoric acid and sodium chloride. Assuming this acid-base reaction were to go to completion…
A. What is the molarity of the resulting 65 mL phosphoric acid solution?
B. If a student tested the actual molarity obtained in lab and found the molarity to be 1.85 M, what is the percent yield of the final materials?

We also must find the balanced equation first.
