What is Density of Pre-1982 Pennies about?

This lab report details an experiment to determine the composition of US pennies minted before 1982 and after 1982. Measurements of mass, volume, and density were taken for samples of pennies from each period using various techniques. The most precise measurements found the density of pre-1982 pennies to be 7.29 ± 0.04 g/cm3 and post-1982 pennies to be 5.94 ± 0.03 g/cm3. However, the calculated compositions from these densities were inaccurate, lying outside the accepted true ranges. Improving the volume me
