Give title of lab; include the procedure, materials list and data table.
Was your original sample a mixture or a pure substance? If it was a mixture, what kind of mixture was it? If it is
a pure substance, what kind of pure substance was it? Explain your reasoning.
When water boils, bubbles can be seen. What substance is in the bubbles? Cite your sources in MLA format.
Determine the percent composition of your original sample. Show all work. This may be neatly written on your
lab report. USE CORRECT NUMBER OF SIGNIFICANT FIGURES.
Determine your percent error using the mass of the original sample versus the mass of all of the individual
components added together. USE THE CORRECT NUMBER OF SIGNIFICANT figures.
Write an error analysis – if your percent error was over 100%, explain why. If you percent error was less than
100%, explain why. If you percent error was 100% explain why. You ALWAYS lose sample when working in the
lab, so you will never have 100% percent error.
Explain how loss of sample can be minimized in the future.
