Physical properties and stoichiometric calculations (see appendix b for ) below are examples of calculations required in organic lab. look up any necessary properties and use that information to answer the following questions. show all work. calculations can be hand written. be mindful of significant figures. a. consider the reaction of 3.4 g of propane with 7.55 ml of molecular bromine (br2) to form 2,2-dibromopropane and hydrogen bromide. the balanced reaction is shown: a. look up the molecular weight of propane and calculate the moles of propane used. b. look up the density and molecular weight of bromine and calculate the moles of molecular bromine used which is the limiting reagent: propane or bromine? show your calculations (calculate the mmols and mg of organic product in both cases.) c. d. calculate the theoretical yield, in grams, of 2,2-dibromopropane. e. suppose that 12.44 grams of 2,2-dibromopropane were actually formed in the reaction. calculate the percent yield of 2,2-dibromopropane.

Read these sentences from the text. near the equator, the tropics receive the most rain on a consistent basis. as a result, the fresh water falling into the ocean decrease the salinity of the surface water in that region. [. .] . . as the salt content of sea water increases, so does its density. what can you infer about how rain affects the density of surface water near the equator?
