Thank you.Cocaine (C17H21O4N; Figure 2) is a natural substance found in leaves of the coca plant, which have been used for centuries as a local anaesthetic and stimulant. Illegal cocaine arrives in the USA either as the pure compound or as the hydrochloride salt (C17H21O4NHCl). At 25oC, the salt is very soluble in water (2.50 kg/L), but pure cocaine is much less so (1.70 g/L). What is the maximum amount of the salt (in gram) that can dissolve in 50.0 mL of water? When a 25 mL 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 litres) is needed additionally to dissolve the formed pure cocaine? Round your final answer off to two decimal points.
