Density is the quotient of two physical properties: mass and volume.

If Mass is needed, given Density then the Volume needs to be found in order to complete the equation: mass = density times volume in compatible units.

For SI units, the units would be

Density = kilograms per cubic meters

Mass = kilograms

Volume = cubic meters

or try this

To find mass divid the density

You can't. As soon as you learn EITHER the mass OR the volume, you'll be able to calculate the other, knowing the density, since the density is their ratio.

Density= mass/volume


Why can two objects with the same mass have different densities?

Volume. Density depends on mass and volume. Density = mass/volume. Things that have the exact same mass can have different densities if the volume associated with either are different.

How can the volume of two substances be the same but the mass be different?

They have different densities.


How do you find the volume and density if only the mass was given?

You cannot. You can determine the third variable if two are given but not determine two when given only one. You have to find some other way to first determine volume or density.

If two solids have the same masses but different volumes they have different densities.


What can you tell about two objects that have the same volume but different masses?

the two objects in question have different densities. The denser object has more mass.


Describe two ways to compare the densities of unknown substances?

You can always compare the densities by the formula d=m/v, where m is the mass and v is the volume . However; a simpler technique is to put the objects in some water . The densities can be compared by how much water each of them will displace.


How do you find the volume ifonly the mass is given?

You can't - not enough information. Mass = volume x density. If you know two of those measurements, you can calculate the third one.


How do you compare the densities of two rock samples?

Divide each rock's mass by its volume. The rock with the higher number is denser. To find the volume, measure the rocks in a graduated cylinder, the one that displaces more water is denser.


Could two objects with the same volume have different masses?

Ceratinly. It depends on their densities.
