Lab Report Follow the standard format for your lab report. Include a calculation of your percent recovery of cinnamic acid based on 85% of your initial material being cinnamic acid and the actual amount of that initial material you weighed. To illustrate your understanding of recrystallization, include a brief procedure for the recrystallization of benzoic acid contaminated with both a little salt and a little sand from water. Benzoic acid is relatively insoluble in cold water, but quite soluble in hot water. Note that you are using only one solvent, so the procedure will be slightly different, and that you have to add a step that is mentioned in the Background section. Can you please answer the second part of the question about the…
