A 32.65-g sample of a solid is placed in a flask. Liquid toluene, in which the solid is insoluble, is added to the flask so that the total volume of solid and liquid together is 50.00 ml. The solid and toluene together weigh 58.58 g. The density of toluene at the temperature of the experiment is 0.864 g/ml. Calculate the density of the solid.
In a combustion reaction 4 moles of C8H18 react with 8 moles of O2. If the actual yield of CO2 produced is 28.16 grams, what is the percent yield?
