In conclusion to the distillation lab‚ I think our data shows that our experiment went well. Our graph resembles the graph in the lab handout (graphs attached to lab notebook sheets). The fractional distillation shows the sharp slope between when the cyclohexane burns off and mostly only toluene remains. The microscale graph seems to be accurate because it shows the large jump where the cyclohexane is burned off. To view the apparatuses used in the experiment look at the attached pictures. To

Conclusion and Evaluation Conclusion In our test we put six different sliced up potatoes chips in solutions. The solution was different concentration of salt and water‚ one was 5% sugar‚ one 10%‚ one 15%‚ one 20% and one 30% salt concentration. We measured the mass of the potatoes chip before and after we put it into the solution. To keep the experiment fair we only changed one variable which was the salt concentration. The results that we got showed the chip went up in mass for 0%

Lab Conclusion on Density In the lab of measuring density‚ precision and accuracy are very key components. Precision is the exactness of a measurement or good technique. Now accuracy is the value that we measured compared to the true value that the book has. Precision and accuracy are important because you need to have good technique and have your value close to the true value to minimize the error analysis. If you do these steps correctly you are a good chemist but if you do them poorly they
