Cocaine (C₁₇H₂₁O₄N) is a natural substance found in cocaleaves, which have been used for centuries as a local anestheticand stimulant. Illegal cocaine arrives in the United States eitheras the pure compound or as the hydrochloride salt(C₁₇H₂₁O₄NHCl). At 25C, the salt is very soluble in water(2.50 kg/L), but cocaine is much less so (1.70 g/L). (a) Whatis the maximum amount (in g) of the salt that can dissolve in50.0 mL of water? (b) If the solution in part (a) is treated withNaOH, the salt is converted to cocaine. How much additionalwater (in L) is needed to dissolve it?

In 1961, scientists agreed that the atomic mass unit (amu)would be defined as the mass of an atom of 12C. Before then,it was defined as the average mass of an atom of naturally occurring oxygen (a mixture of 16O, 17O, and 18O). The current atomic mass of oxygen is 15.9994 amu. (a) Did Avogadro’snumber change after the definition of an amu changed and, if so,in what direction? (b) Did the definition of the mole change?(c) Did the mass of a mole of a substance change? (d) Before1961, was Avogadro’s number 6.021023(when considered tothree significant figures), as it is today?
