Q:

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

A:

Quick Answer

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.

Full Answer

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.

  • Q:

    How do you find mass?

    A:

    Mass is equal to density times volume, or m = Dv, since density is equal to mass divided by volume, or D = m/v. Mass is denoted by the symbol "m," and its SI units are kilograms.

  • Q:

    What is air density?

    A:

    Air density is the mass of air per unit of volume it occupies, and it is expressed in kilograms per cubic meter when using the metric system. In the free atmosphere, air density decreases when temperature increases or when the air is humid. However, air density increases when pressure increases.

  • Q:

    How do you use mass (in mg) to determine volume occupied?

    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.

  • Q:

    What tool is used to measure density?

    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.
