Question

1.      An entrepreneurial group of UCLA students starts a bubble gum company. The first variety of gum they decide to sell is banana and the flavor used in the gum is made according to the following chemical equation:

The student starts with 0.28 g of isopentyl alcohol.

a.       Calculate in moles and grams how much acetic acid would be needed to complete the reaction

b.      Calculate in moles and grams the theoretical yield of isopentyl acetate assuming the alcohol is the limiting reagent

c.       The team%u2019s actual yield in grams is 0.22 grams. What was the percent yield?

Explanation / Answer

moles of alcohol=moles of acid

so moles of acid=0.28/88.2

=3.17*10^-3

so mass=3.17*10^-3*60.1

=0.1907 grams

b)moles of isopentynyl acetate=3.17*10^-7

mass=3.17*10^-3*(88.2+60.1-18)

=0.4131 grams

c)%age yeild=(0.22/0.4131)*100

=53.25 %
