The stockroom has a bottle with a solution of phosphoric acid labeled: 91.7% H₃PO₄ by mass (d = 1.69 g/mL). It also has a bottle with a solution of sodium hydroxide labeled 12.0% NaOH by mass (d = 1.133 g/mL). How many mL of the NaOH solution are required to completely react with 10.00 mL of the H₃PO₄ solution? The equation for the reaction is
