using the picture of the reaction above and the
following given experimental data from "Reactions of Butanols with
HBr" lab:
mass of 1-butanol used=5.35g
crude mass extracted (actual yield)=1.70g
a) calculate the theoritical yield of the extracted
crude mass.
b) calculate the %yield of the reaction.
please solve it correctly with explanation and I'll
provide good rating
thank you

You will be observing a reaction in this lab. As with most reactions, this reaction occurs by the breaking of some bonds in the reactants and the formation of new bonds in the products. During the reaction, the gas that is produced will fizz away. After the reaction is complete, one of the products can be removed. Then you will determine the mass of the other product this will be your actual (or experimental) yield. You will compare this value...
