How do I calculate density?


Without specialized equipment, it is impossible to measure a substance's density directly. However, density can be calculated by first weighing and then finding the volume of an item.

  1. Find the mass of the item

    Place the item on an accurate scale, and record the mass in grams.

  2. Find the volume of the item

    If the item is a regular shape like a cube, volume can be calculated using a mathematical formula. If the item is an irregular shape, it must first be broken down into regular shapes before the volume can be calculated. Record the volume in cubic centimeters.

  3. Calculate density

    To find the density of the item, divide the mass by the volume to determine density in units of grams per cubic centimeter.

Q&A Related to "How do I calculate density?"
Density is mass per unit area. Density (rho) is calculated as Mass/Area. For some liquids, it is calculated as Mass/Volume. Density is measure of number of molecules.
1. Find the volume of your object (if you don't already know this information) Measure the length, width and height of your object (for square or rectangle objects) and multiply all
1. Distinguish between volume and density. Volume (v) - It's the space occupied by an 3-dimensional object enclosed by a close boundary. Density (ρ) - It's simply mass/unit volume
Density is calculated by the mass divided by the volume.
