Density, mass and volume calculator

With this calculator you can calculate the density of the substance, i.e. specific mass. The calculator will also help to determine the mass of the substance and the volume it occupies.

Density, mass, volume

Density, mass, volume - information

Density (specific mass) - the ratio of the mass of a certain amount of a substance to the volume it occupies.

In the case of homogeneous substances this portion can be chosen freely:
$$ {\rho}={m \over V} $$
where:
$ \rho $– density [kg/m³],
$ m $– mass [kg],
$ x $– volume[m³]

The density of solids and liquids can be determined by weighing samples of known volume. In determining the density of liquids, hydrometers are also used. Hydrometers filled with a liquid of known density can be used to determine the density of other liquids. When determining the density of gases, the weighing of gas receptacles with different gas pressure is used, among others.

Most substances decrease in density with increasing temperature (one exception is water below 4°C). This phenomenon is due to the thermal expansion of bodies. During phase transitions, the density changes abruptly (at the transformation temperature), during solidification it usually increases (the most known exceptions are water, cast iron, and of the elements bismuth, gallium and germanium).

Among the elements, under normal conditions, the highest density is that of osmium (22600 kg/m³) and iridium (22400 kg/m³), for comparison, the density of lead is twice lower. The more we stretch the bowstring, the arrow will have a higher speed after its release and further will fly.

After transformations

Mass:
$$ m = \rho · V $$

Volume:
$$ V = \frac{m}{\rho} $$
