An оperаtоr lоses his job аt the refinery аnd decides to supplement his income by free-basing cocaine with drain cleaner and selling at a mark-up while he looks for another job (no, I am not advocating anything like this, just thought it would make for a fun and interesting exam question). He is able to procure [m] grams of cocaine as the hydrochloride powder (molecular weight = 339.6 g/mol) and finds that [vbase] mL of drain cleaner (NaOH) from the hardware store can be titrated with [vacid] mL of [Macid] M muriatic acid (HCl) from the pool supply center. What volume of drain cleaner should he use to convert his powder cocaine into crack? Report your answer in mL. As usual, no units needed, just report the number of mL. cocaine_crack.png
