Q:

# What is the formula that indicates that volume equals mass divided by density?

A:

The formula for density, which is mass divided by volume, can be manipulated to have the volume as the unknown. Given the mass and the density, the volume can be found by dividing the mass by the density.

Know More

The International System of Units (SI) unit used for density is kilogram per cubic meter. The densities of common substances are known constants. Thus, looking for either the mass or the volume is easy by simply using the formula above. Density can be observed when a helium balloon escapes and floats through the air. This happens because the air around the balloon is more dense than helium.

• A:

Density and mass are mutually dependent physical properties, with density being equal to the amount of mass per unit of volume of any particular object or substance. The mass of any object depends entirely on its overall density, with denser objects having greater mass, for the same volume, than less-dense objects. The mass of an object with uniform composition changes if pieces are added or removed, but its density remains constant. Meanwhile, barring any melting or evaporation, the density of an object tends to change with changes in temperature, while the mass remains the same.

• A:

To use the known mass of a substance to calculate the volume occupied by that substance, divide the mass by the density of the substance. The units in which density is expressed must be the same as those used to measure mass and the volume.

• A:

Density is defined as mass per unit volume, so it is necessary to measure both the weight and volume of an object to determine its density. Use a scale to measure the object's weight. A ruler can be used to measure the dimensions of an object and calculate its volume.
