Mass is how heavy something is, volume tells you how big it is, and density is mass divided by volume. To get density, divide mass by volume. These may include beakers, a volumetric flask, an Erlenmeyer flask, and a graduated cylinder. Then slide across that row to '0.
Assume that the density of water makes a negligible contribution to the overall uncertainty in the values calculated. He summons Archimedes, who decides to use density to determine the metal. If ice did not float, it would sink to the bottom, allowing more ice to form and sink, until the lake froze solid!
Density of aluminum and brass cylinders using three different methods of volume measurement Part 0: Measure metal cylinder masses.
