www.kpu.caSTOICHIOMETRY AND PERCENT PURITY Many samples of chemicals are not pure. We can define percent purity as mass of pure compound in the impure sample total mass of impure sample x 100 If an impure sample of a chemical of known percent purity is used in a chemical reaction, the percent purity has to be used in stoichiometric calculations.
Tutorial 3 THE MOLE AND STOICHIOMETRY
www.eiu.eduStoichiometry is the study of the relationships of quantities of substances in a chemical reaction. Consider the reaction: (1) FeCl ... Calculate the percent purity of the silver sulfate sample. 19) 1.52 g of aluminum reacted with excess chlorine gas to give an 83.5% yield of aluminum chloride. Calculate this mass of aluminum chloride.
Traditional Undergraduate Experiment: Synthesis of Aspirin
www.magritek.comStudents synthesise aspirin and evaluate the purity of their product using 1H-NMR spectroscopy. This laboratory introduces students to aspects of practical organic chemistry including synthesis, crystallization, stoichiometry, and percent yield. 1 therefore students must determine the purity of their product. Typically this is done using thin layer
