Question
Use the following atomic weights and quantities to calculate the overall % yield of 4-bromo-4'-pentyllbiphenyl. Remember that your yield must be based on the stoichiometry (balance
the equation!), the limiting reagent, and that grams must be converted to moles. Filling out most of the chart will help. Give only two significant digits in your answer. If after rounding
the answer is a whole number, do not include a decimal point.
