Question

SYNTHESIS OF ALUM If 500g of laboratory grade aluminum potassium sulfate cost $8.25, is it cost effective to make the aluminum potassium sulfate yourself? Consider the following data and the percent yield(68.6%) when determining the answer. Al foil cost $1.69 for 20 sq-ft and 1 square foot weighs 3.75g. Sulfate acid solution, 3M cost $9.80 for 500mL. Potassium hydroxide solution, 3M costs $12.80 for 250mL. When calculating the answer, only consider the amount of chemical needed and not the capital cost of the chemicals, equipment or labor time. Part A. What is the cost of the chemicals used to obtain the alum crystals in the experiment? Part B. Using the conversion factor of chemical cost (part A) in relation to specific yield, calculate the cost of making 500.0g of aluminum potassium sulfate. Part C. Is this laboratory method cost effective? why or why not? These are the only numbers I got from the experiment. Mass of aluminum foil=0.7523g Mass of crystals=9.0502 Percent yield=68.6% Please try to figure it out to the best of your ability and as soon as possible! Much thanks
