2.37 Why are empirical formulas preferred for describing polymer molecules?
What number of molecules (or formula units) are present in 1.00 g of each of the compounds in Exercise 51?
Cyclopropane is an interesting hydrocarbon. Instead of havingthree carbons in a row, the three carbons form a ring, asshown in this perspective drawing (see Figure 2.18 for a priorexample of this kind of drawing):Cyclopropane was at one time used as an anesthetic, but itsuse was discontinued, in part because it is highly flammable.(a) What is the empirical formula of cyclopropane? Howdoes it differ from that of propane? (b) The three carbon atomsare necessarily in a plane. What do the different wedgesmean? (c) What change would you make to the structureshown to illustrate chlorocyclopropane? Are there isomers ofchlorocyclopropane?

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?
Calculate Moleculer mass of the H2SO4

The molecular mass of a compound of interest is 60 g/mol. The empirical formula of this compound is CH2O. Enter the molecular formula of the compound in C#H#O# order.
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)
