•         Calculate your percent error from your calculated mass of NaCl.

•         Write a conclusion-What did mass of NaCl did you produce? How does this compare to your hypothesized amount of NaCl? Use your percent error to support. What errors could have affected your results and why would they affect them? How could what you learned in this lab be applied in the real world? What is a new experimental question you would like to complete now?
