Problem

An irregular solid has a measured mass of 165.0 g ± 0.5 g. When submerged, it displaces 19.5 cm³ ± 0.2 cm³ of water. Tabulated densities (in g/cm³) for candidate materials are: • Brass 8.4–8.7 • Bronze 8.7–8.9 • Nickel 8.9 Considering the measurement uncertainties, list all candidate materials that cannot be ruled out.
