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 × 10-⁹ at 35.0°C). Calculate the pH of a 40.0-mg/mL aqueous dose of papHCI prepared at 35.0°C. Kw at 35.0°C is 2.1 x 10-¹4. pH =
