Now assume that you started with only 1.80 g of sodium benzoate. Assuming that the reaction proceeds to form benzoic acid, what would your theoretical yield be? Use two decimal places.
Pretend you run a reaction and your theoretical yield is 5.25 grams, but you only isolate 4.25 grams. What is your percent yield? Use one decimal place. Use one decimal place.
