2. Some guidelines… You will be finding the density of two different substances – one solid and one liquid (DI water). Record the data in a data table You are free to use any of the equipment in the open cabinets or on the lab tables. If there is a piece of equipment that you need and cannot find, please let me know.

3. Analysis Use the given data table to identify your solid. Find the percent error of your experiment using the following formula:

4. Known Density of Unknowns DI Water 1.00 g/cm 3 Aluminum 2.702 g/cm 3 Tin 7.28 g/cm 3 Platinum 21.45 g/cm 3 Copper 8.96 g/cm 3 Tin 7.26 g/cm 3 Titanium 4.51 g/cm 3 Zinc 7.14 g/cm 3 Lead 11.3 g/cm 3 Lithium.53 g/cm 3 Acrylic 1.21 g/cm 3 Glass 2.58 g/cm 3
