Question
Cocaine(C17H21O4N) is a natural substance found in the leaves of the coca plant, which has been used for centuries as a local anesthetic and stimulant. Illegal cocaine arrives in the USA either as a pure compound or as the hydrochloride salt(C7H21O4NHCl). At 25 degrees celsius, the salt is very soluble in water(2.59kg/L), but pure cocaine is much less so(1.70g/L)
a. What is the maximum amount of salt in grams that can dissolve in 50.0mL of water?
b. When a 25mL aqueous solution that contains 62.50 g of the salt is treated with NaOH, the salt is converted to pure cocaine. How much water in liters is needed additionally to dissolve the formed pure cocaine,
