The student weighs out 0.18 g of an diprotic unknown acid and dissolves it in approximately 50 mL of water. She adds a few drops of phenolphthalein and titrates the acid sample with the NaOH solution she standardized in question 2. She determines that 21.50 mL are required to reach the end point a. What is the molar mass of the acid?
