2. A 0.5192 g sample of a solid monoprotic acid (molar mass of 180.0 g/mole) was dissolved in water and titrated by the addition of an aqueous solution of NaOH. To reach the equivalence point, 15.96 mL of NaOH solution were required. a. Calculate the molarity of the NaOH solution. b. Write the generic representation of the reaction of a monoprotic acid with NaOH. Then, calculate the molar mass of an unknown monoprotic acid if 15.64 mL of the NaOH solution from (a) was required to titrate 0.8256 g of the acid. Reaction: c. Write the generic representation of the reaction of a diprotic acid with NaOH. Then, calculate the molar mass of an unknown diprotic acid if 15.64 mL of the NaOH solution from (a) was required to titrate 0.8256 g of the acid. Reaction:

2. A 0.5192 g sample of a solid monoprotic acid (molar mass of 180.0 g/mole) was dissolved
in water and titrated by the addition of an aqueous solution of NaOH. To reach the
equivalence point, 15.96 mL of NaOH solution were required.
a. Calculate the molarity of the NaOH solution.
b. Write the generic representation of the reaction of a monoprotic acid with NaOH. Then,
calculate the molar mass of an unknown monoprotic acid if 15.64 mL of the NaOH
solution from (a) was required to titrate 0.8256 g of the acid.
Reaction:
c. Write the generic representation of the reaction of a diprotic acid with NAOH. Then,
calculate the molar mass of an unknown diprotic acid if 15.64 mL of the NaOH solution
from (a) was required to titrate 0.8256 g of the acid.
