Use the following atomic weights to calculate how many grams of phenylacetic acid are required to make the given amount of dibenzyl ketone with the expected % yield. Assume the iron is used in excess. Don't forget about the stoichiometry! Give only two significant digits in your answer. C = 12, H = 1, 0 = 16 phenylacetic acid + iron dibenzyl ketone formula formula weight grams 2.308 moles theoretical yield (g) % yield 67 Answer:

Given 73.7200 g of caffeine and the following atomic weights, how many mmoles (millimoles) of caffeine do you have? Remember that a mmoles is 1/1000 of a mole. Round to a whole number answer with no decimal or units. C = 12, H = 1, N =14, O = 16 2) Question text Assuming that the manufacturer claimed that your tea had 26 mg of caffeine per gram, that you weighted out 15.2090 g of tea, but you isolated only...

Use the following atomic weights and quantities to calculate the overall % yield of dibenzyl ketone. Remember that your yield must be based on the limiting reagent, and that grams must be converted to moles. For problems not involving a one to one stoichiometry it may be easier to calculate the theoretical yield in grams from both reagents to determine which is truly the limiting reagent. Filling out most of the chart will help. Give only two significant digits in...
