1. What percent error is sustained in your final value (for the density of the solid) by the method of Archimedes' principle if you merely take the value for the density of water as 1.00 g/cm3 and neglect the variation with temperature? Show the calculation.
2. Which method of determining density do you prefer? Which is more accurate? Which is more precise? What are the advantages and disadvantages of each method?
3. For each method, what are some possible systematic errors you encountered?
