Ma huang, an extract from the ephedra species of plants, contains ephedrine. The Chinese have used this herb more than 5000 years to treat asthma. More recently the substance has been used in diet pills that can be purchased over the counter in herbal medicine shops. However, very serious concerns have been raised regarding these pills following reports of serious heart problems with their use. (a) Write the molecular formula for ephedrine, draw its structural formula, and calculate its molar mass. (b) What is the weight percent of carbon in ephedrine? (c) Calculate the amount (moles) of ephedrine in a $0.125-\mathrm{g}$ sample. (d) How many molecules of ephedrine are there in $0.125 \mathrm{g} ?$ How many C atoms? (FIGURE CANNOT COPY)
