Chemistry

Upon graduation, in a misguided attempt to pay off your studentloans more quickly you become involved in the trade of illicitnarcotics. Your usual supplier gets eliminated by the competitionand you are forced to procure your product from a new supplier. Youpurchase what your new supplier claims to be codeine (C18H23NO3) of>99% purity but a simple (and ill-advised) taste test leaves yoususpicious that it has been thinned with sucrose (C12H22O11). Youlook up the heat of combustion of codeine (2327 kcal/g) and that ofsucrose (2222 kJ/mole). You then take 1.0g of your product and findthat it releases 2095 kcal upon combustion. What is the purity ofyour sample, assuming it contains only codeine and sucrose?
