Chemistry density lab answers.

The densities of solids and liquids are expressed as g/mL or g/cm ^3. For gases the g/L unit is favored since their densities are usually smaller. When a substance has a density less than that of water (1.00 g/mL) it will float and when the density is greater than the density of water, it will sink.Measurement Packet #147-162 Penny Density Lab Learn with flashcards, games, and more — for free.Explore the concept of density and how it relates to mass, volume, and buoyancy in this interactive simulation.
