You are preparing standard acid and base solutions for the laboratory, using potassium hydrogen phthalate (KHC,H,O,, abbreviated KHP) as the primary standard. KHP (molar mass = 204.22 g/mol) has one acidic hydrogen. You prepared solutions of both NaOH and HCI. It took 22.65 mL of the NaOH solution to titrate (react exactly with) 1.55 g KHP. It then took 27.35 mL of HCI solution to titrate 25.00 mL of the NaOH solution. What is the molarity of the HCI solution?

Carminic acid, a naturally occurring red pigment extracted from the cochineal insect, contains only carbon, hydrogen, and oxygen. It was commonly used as a dye in the first half of the nineteenth century. It is 53.66% C and 4.09% H by mass. A titration required 18.02 mL of 0.0406 M NaOH to neutralize 0.3602 g carminic acid. Assuming that there is only one acidic hydrogen per molecule, what is the molecular formula of carminic acid?
