Determine the density of a solid or liquid 2. Graph data 3. Use the factor-label method for density calculations.
Density is a number that relates th e mass of an object to the space it takes up.
Some types of matter are more tightly packed than others, and therefore have higher densities. And density is a useful physical property for identifying and classifying materials. Density is the bridge or connecting link between mass and volume. To calculate the density of an object, or a definite amount of liquid, you need only divide the mass by the volume, and round off the answer to the appropriate number of significant figures. You will learn about GAS densities later in the course.
