A sample of an organic compound (a nonelectrolyte) weighing 1.35 g lowered the freezing point of 10.0 of benzene by 3.66 C. Calculate the molar mass of the compound.
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?
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 (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 salt (in gram) that can dissolve in 50.0 mL of water? [1 mark.] 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 liters) is needed additionally to dissolve the formed pure cocaine? Round your final answer off to two decimal points. C17H21O4NHCl(aq) + NaOH(aq) → C17H21O4N(aq) + H2O(l) + NaCl(aq)
