Modeling Isotopes PreLab - Honors Chemistry

Pre-Lab1. On your analysis sheet, make “Data Table 1” to record the total mass (g) of a group of ten pre-1982 penniesand then a group of ten post-1982 pennies. Include a place to record the average masses of each type ofpenny as well. You will also need another table, “Data Table 2,” to record the identity of your container,mass of empty container, the total mass of the container and pennies, and the mass of the pennies inside thecontainer. A space has been provided for you to make this table on your analysis sheet.Procedure2. Obtain 10 pre-1982 and 10 post-1982 pennies, and two sealed containers with pennies inside.3. Record the masses of each group of pre-1982 and post-1982 pennies on Data Table 1. Determine theaverage mass of each type of penny and record it as well.4. Record the identity of your sealed penny containers, along with the empty container masses (provided byyour instructor) on Data Table 2.5. Record the total mass of the sealed container and pennies on Data Table 2.6. Calculate the mass of the 10 pennies inside the container. Record on Data Table 2.2
