Papaverine hydrochloride (abbreviated papH+Cl-; molar mass = 378.85 g/mol) is a drug that belongs to a group of medicines called vasodilators, which cause blood vessels to expand, thereby increasing blood flow. This drug is the conjugate acid of the weak base papaverine (abbreviated pap; Kb = 8.33 X 10 -9 at 35.0°C). Calculate the pH of a 30.0-mg/mL aqueous dose of papH+Cl- prepared at 35.0°C. K w at 35.0°C is 2.1 X 10 -14.
