Using the periodic table or some other reference look up the. M r of CaO 401 160 561. This problem has been solved.
Mass of product molecular weight of product moles of limiting reagent in reaction stoichiometry of product where.
Moles total mass to find how many moles magnesium you had to start with. Use the molar mass of the product to convert moles product to grams of product. The theoretical yield is the yield youd get for a 100 reaction - ie. Calculate the percent yield.
