QUESTION 6 Cocaine (C17H2104N) and cocaine hydrochloride (C17H2104N-HCI) are interconvertible to each other according to given reaction. At room temperature 125 g of C17H2104N-HCl is dissolved in 50 mL of water, then the solution is reacted with NaOH. How much pure cocain could be obtained? (Aqueous solubility of cocaine = 1,70 g L-') C17H2104N HCl(aq) + NaOH(aq) C17H2104N(aq) + H2O(aq) + NaCl(aq) 1H: 1.008 g mol-'; 6C: 12.01 g mol-'; N: 14.01 g mol-'; 80: 16.00 g mol-'; 17Cl: 35.45 g mol-' QUESTION 7 4 mL of concentrated HCl acid solution was diluted to 200 ml. Then 55 mL sample of the diluted solution requires 25.3 mL of 0.0872 M NaOH solution for its titration. What is the molarity of the initial HCl solution
