What is the difference between density and weight?

Density is the amount of matter per unit of volume, while weight is the force exerted on an object due to gravity.

How is density calculated?

Density is calculated by dividing the mass of an object by its volume.

Solids use cubic cm, while liquids and gases use liters for volume measurement.

To find the mass of an object, convert volume units to match density, then use the formula mass equals density times volume.

A cube of copper with a mass of 150 g and volume of 16.7 cubic cm has a density of 8.98 g per cm cubed.

Density is a measure of how much matter is packed into a given volume, calculated by dividing mass by volume. This concept explains why a pound of feathers and a pound of bricks, though weighing the same, differ due to their density.
Different substances have varying densities; for instance, air has low density, while lead is much denser. Understanding density is crucial in determining how much space a certain amount of a substance will occupy, with solids using cubic cm and liquids/gases using liters for volume measurement.

A pound of feathers and a pound of bricks weigh the same, but the difference lies in their density. Density is the amount of matter per unit of volume, calculated by dividing mass by volume.
Air has low density, with 10 grams of air occupying over 8 liters of space. In contrast, 10 grams of lead would take up less than 1 cubic cm. Solids use cubic cm for volume measurement, while liquids and gases use liters.
Calculating density involves dividing mass by volume. For example, a cube of copper with a mass of 150 g and volume of 16.7 cubic cm has a density of 8.98 g per cm cubed. To find mass, convert volume units to match density, then use the formula mass equals density times volume.
