Results: Suppose that you isolate 4.0g of sand, 2.6g of benzoic acid, calculate the percentage of each components of the mixture If the original masses are 4.3g of sand, 3g of benzoic acid and 2.7g of NaCl Use the following formula to calculate % error: %error=acceptedvalueacceptedvalueexperimentalvalue100 Percent benzoic acid: Percent NaCl: 2. Obtain the percent composition of the teacher's mixture. Calculate the percent error your results. Show your calculations. Sand \% error: Benzoic acid \% error: NaCl% error: 3. Explain in your own words why the benzoic acid was able to be separated from the NaCl by cooling the solution. 4. A lab team rushed through the lab and did not sufficiently cool the recrystallizing mixture of benzoic acid/water. How would this affect their value for the \% of benzoic acid in the originial mixture? Explain. 5. If your result for % sand was higher than in the original mix, what are possible sources for this experimental error
