How do you calculate density?

Answer 1

Mass over Volume.

D=M/V

Use metric, so mass in grams or KG and Volume in mL or cc (cubic centimeters) mL and cc are the same measurement, 10 mL or water is the same as 10 cc.

If you used grams and mL, you would get an answer like x g/mL.

For example:

If you have 1 mL of water and it weighs 100 grams, you dive the 100 grams by 1 mL, so the density is 100 g/mL. (water's density is ACTUALLY about 1)

that's a true fact {kl}

The density of water is not 1 because it must have units of measurement. It is about 1 gram per cc or 1 gram per ml or 1 kilogram per litre. The density of water can also be given [correctly] as approximately 1000 grams per litre or 0.001 kg per cc.

Answer 2

Density is the ratio of an object's mass divided by its volume. The standard international unit to measure density is kilograms per cubic meter (kg/m3). The addition of "relative" to the term is unnecessary unless you are comparing your subject material to something other than the standard 1 kg/l which is the density of pure water.

Answer 3

Relative density is the ratio of the density of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water.

The formula for relative density can be shown as:

ρsubstance/ρreference

Where ρ is the Greek letter rho, representing density - ρsubstance refers to the density of the substance in question, and ρreference represents the density of the reference.

Answer 4

Relative density, sometimes called specific density, is the ratio of the density of a substance to the density of a given reference material.

Answer 5

density = mass/volume

The international units used are grams per cubic centimeter or Mg (mega grams = thousands of kilograms) per cubic meters.

Answer 6

Usually relative density is the density relative to water which has a density of 1000kg/m3

Therefore if you have a relative density of 1.2 the actual density is 1.2 x 1000=1200kg/m3

Answer 7

Density = mass / volume
