Because every material has its own density. Examples:Solid - water - noble gas
Copper has a density of 8950 kg/m3 = 8.95 kg/dm3 = 8.95 g/cm3.
Water has a density of 1000 kg/m3 = 1000 g/L = 1.000 kg/dm3 = 1.000 kg/L = 1.000 g/cm3 = 1.000 g/mL.
Helium has a density of 0.1785 kg/m3 = 0.1785 g/L = 0.0001785 kg/dm3 = 0.0001785 kg/L =
0.0001785 g/cm3 = 0.0001785 g/mL.
density = mass / volume
To measure the volume of 20 g of alcohol, you would need to know the density of the specific alcohol. Then, you can use the formula: volume = mass/density. Once you have the density, divide 20 g by the density to find the volume in milliliters.
Density is a physical property that is unique to each element and can be used to identify it. By measuring the density of a substance and comparing it to known values in the periodic table, you can determine the most likely element present.
Density can be defined that way, but it is more common to use another kind of density: mass per unit volume.
Use a mass balance to find the mass then find the volume by V=mass/density.
Mass = Density -------- volume
density= mass/volume
The density of a substance can be measured in a laboratory.
The principle of density was discovered by Archimedes. To calculate density, we use the equation Density = mass/volume.
Females use the concept of density during pregnancy. They gain weight, ie density, and inside them a growing life occurs. Humans also use density during swimming and water play to remain buoyant.
we use it by making things strong
Let's test the density of that wallboard with this two by four.
Yes, you can use density to predict whether an object will float or sink in water. If the density of an object is less than the density of water (1 g/cm³), it will float. If the density of an object is greater than the density of water, it will sink.
If the object's density is greater than the density of the liquid in which it is placed, it will sink. If the density is less, it will float. You can use math to calculate the density, if you know an object's mass and volume. Density is defined as mass divided by volume.
Fish use density in order to move in the water since they do not have lungs. When the density of water keeps changing, fish use it to move and thereby using less energy.
Density is calculated by dividing the mass of an object by its volume. The formula for density is: Density = mass / volume. The SI unit for density is kg/m^3.
They would use density to measure the volume of a substance :)
