Use a scale to find the mass of several marbles.
Put some water in a graduated cylinder. Take a reading.
Place all the marbles in the grad. cylinder with the water, which will rise.
Take another reading. Make sure the marbles are completely submerged.
Subtract the 2 readings. This gives the volume of the marbles. This is called the water displacement method.
Divide mass by volume. This gives you the density.
The mass divided my the volume determine the density of an object
Density can be used to determine the mass and the volume of a given solid.
To determine the relative density of a substance, you can divide the density of the substance by the density of water. The relative density is also known as specific gravity and helps compare the density of a substance to that of water.
The formula for density is an object's mass, divided by its volume. If you have both those quantities, you can determine the object's density.
You multiply the density by the volume.
Mass = Density Volume
The two factors that determine a material's density (such as that of wood) are its mass and volume.
The density of the mineral compared to the density of water will determine if it floats or sinks. If the mineral has a lower density than water, it will float; if it has a higher density, it will sink.
Density in general is found by Mass divided by the volume
density=mass divide by volume
To determine the density of an element, you would need to measure its mass and volume. The density of an element is calculated by dividing its mass by its volume. The formula for density is: Density Mass / Volume. By measuring the mass and volume of the element, you can then calculate its density.
All you can do with mass and volume is to determine the density of the substance. density = mass / volume or p=m/v after you determine the density, you can look on any density table and find the substance you are looking for. good look. -julio
