The measurement of how much mass is contained in a given volume is called

Density. Remember that m/v formula they talk about in science class? That's the one.

Right. density = grams/mL or g/L or some other mass/volume unit

The measurement of how much mass is contained in a given volume is called density.

To calculate density, you need to know the mass of the substance and its volume. The formula for density is:

Density = Mass / Volume

The unit of density depends on the units used for mass and volume. For example, if the mass is measured in grams and the volume is measured in cubic centimeters, the density would be in grams per cubic centimeter (g/cm³).

To determine the mass of an object, you can use a balance or a scale. Place the object on the balance or scale, and it will provide the mass reading.

To find the volume of an object, it depends on the object's shape. For regular-shaped objects like cubes or rectangular prisms, you can measure the length, width, and height and then use the formula Volume = Length × Width × Height. For irregular-shaped objects, you can use techniques like water displacement to measure the volume.

Once you have the mass and volume values, you can calculate the density by dividing the mass by the volume.
