If measured in centimeters, the answer will be in cubic centimeters (cm³). Mass is measured in grams. The units for density will be g/cm³. Arrangement of atoms in different metals is similar.

If something seems light for its size (like a bag of cotton or pumice rock), then we say it has low density. Mass is the amount of matter in an object. Volume is how much space the object takes up.

Researchers have published a comprehensive review in Chemical Reviews on electron density-based methods. Electron density topology is a concept of theoretical chemistry but there is nothing ...

In the hot (yellow) water, the water molecules are slightly further apart than in the cold (blue) water. The hot water is less dense and floats on the cold water. When the cold water is placed on top, ...

The physical properties of seawater include both 'thermodynamic properties' like density and freezing point, as well as 'transport properties' like the electrical conductivity and viscosity.
