Patrick Mahomes was separating 300 mg of a three-component mixture containing an amine, a carboxylic acid, and a neutral compound. Tom Brady borrowed his 10% HCl solution and left it nearly empty so that Patrick Mahomes ran out of the 10% HCl solution during the acidification of the aqueous fraction containing the carboxylate ion. He was only able to obtain pH=5 of the solution that should have been brought to pH=2. Calculate the amount of protonated carboxylic acid Patrick Mahomes generated, assuming that the starting mixture contained equal amounts of all components and the pKa of the carboxylic acid is 4.5. Report to the hundredths place.
