Final answer:

Density is the mass per unit volume of a substance. It can be calculated by dividing the mass of the substance by its volume. Density can be measured using a balance and a graduated cylinder, and it can be used to predict the behavior of substances.

Step-by-step explanation:

Density is an important characteristic of substances. It is the mass per unit volume of a substance or object. Density can be calculated by dividing the mass of the substance by its volume. For example, if an object has a mass of 20 grams and a volume of 10 cm³, its density would be 2 grams/cm³.

Mass and volume can be measured using a balance and a graduated cylinder respectively. To measure the volume of an irregularly shaped object, the water displacement method can be used. This involves measuring the volume of water before and after immersing the object in a graduated cylinder and calculating the difference.

Density can be used to predict the behavior of a substance. For instance, if the density of a substance is greater than the density of a liquid, the substance will sink into the liquid. On the other hand, if the density of a substance is less than the density of a liquid, the substance will float on the liquid.
