Those who are working in the laboratory may already know and have a well understanding about density, whereas those who are new may still confuse about it. Density is a physical property of matter that describes how much mass is contained in a given volume. In essence, it is a measure of how tightly packed the molecules of a substance are. The density of a substance is usually expressed in units of grams per cubic centimeter (g/cm^3) or kilograms per cubic meter (kg/m^3). Understanding how to determine density is essential for various scientific and engineering applications. In this article, the main focus will be on uncovering the mystery behind finding the density of an object when its volume is unknown.
To uncover the mystery of finding an object’s density without knowing its volume, the first step is to weigh the object using a precise scale. This measurement provides the mass of the object in grams. Next, a graduated cylinder or a beaker filled with water is required. Carefully submerge the object in the water, ensuring that it is completely submerged and no air bubbles are trapped. Record the new water level and subtract it from the initial water level to determine the volume of water displaced by the object. This displaced volume is equivalent to the volume of the object.
To complete the puzzle, simply divide the mass of the object by the volume of the displaced water. The result of this calculation is the density of the object. This technique is widely used to determine the density of irregular objects or objects with intricate shapes. By employing this method, scientists and engineers can effortlessly uncover the density of various materials, aiding in the analysis of their properties and behaviors within different fields.
How to Find Density With Unknown Volume
Density is a physical property that measures the mass of a substance per unit volume. It is a useful property for identifying and comparing substances, as well as for making calculations involving weight, volume, and mass. In order to find the density of a substance, you need to know its mass and volume. However, if you do not know the volume of a substance, there are a few ways to find its density.
- Use a graduated cylinder to measure the volume of water that is displaced by the substance. The volume of the displaced water is equal to the volume of the substance.
- Use a balance to measure the mass of the substance. The mass of the substance is equal to the mass of the displaced water.
- **Calculate the density of the substance using the following formula:**Density = mass / volume

How do you find the density of a liquid?
You can use a hydrometer to find the density of a liquid. A hydrometer is a device that is used to measure the specific gravity of a liquid. The specific gravity of a liquid is the ratio of the density of the liquid to the density of water. To use a hydrometer, you will need to:
- Place the hydrometer in the liquid.
- Read the specific gravity of the liquid from the hydrometer.
- Multiply the specific gravity by the density of water to find the density of the liquid.
How do you find the density of a gas?
You can use a gas pycnometer to find the density of a gas. A gas pycnometer is a device that is used to measure the mass of a known volume of gas. To use a gas pycnometer, you will need to:
- Fill the gas pycnometer with the gas.
