In order to find the density of the rock, the student should follow the steps highlighted below.
Steps in determining density of a rock
Weigh the rock using a scale to find out how heavy it is in grams. Ensure that the measurement is very precise.
Find out how much space the rock takes up: There are a few ways to figure out how big an irregularly shaped object, like a rock, is. There are two usual ways:
"Use water to measure volume: Pour water into a cylinder and write down how much there is at the start. " Gently put the rock in the water, and make sure there are no air bubbles stuck.
Find out how much water the rock is pushing out of the way now. Subtract the starting volume from the ending volume to find the volume of the rock.
Archimedes' principle: First, weigh the rock in the air. Then, weigh it again when it's completely underwater. The change in weight when a rock is in water is the same as the weight of the water that the rock pushes aside. Find the volume of the rock by dividing its weight by the density of water, which is usually 1 gram per cubic centimeter.
To find the density of a rock, divide its mass (in grams) by its volume (in cubic centimeters or milliliters). Density = Mass / Volume
Density is the amount of mass in a certain amount of space. It is calculated by dividing the amount of mass by the amount of space it takes up.
Ensure that the measurements for mass and volume are the same (like both in grams or both in kilograms, both in cubic centimeters or both in milliliters).
After calculating the density, write it in the right units. Density is usually measured in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).
