Ok, say you have a hollow log. Now say you stuffed it with cotton. The more that is in the log, it gets heavier. That is how density works.
To work out the density of an object, you need to know its mass (weight) and volume. Density is calculated by dividing the mass of the object by its volume.
The density of a potato is approximately 0.79 grams per cubic centimeter.
To calculate the mass of an object, you can use the formula: mass = density x volume. Multiply the density of the object by its volume to find the mass. Make sure the units for density and volume are compatible, such as grams per cubic centimeter for density and cubic centimeters for volume.
There are many types density, like true density, tap density, bulk density etc. Can use analyzer like G-DenPyc 2900 gas pycnometer analyzer to measure them. Aerometer or Hydrometer for density of liquids, Dasymeter for density of gases and Resonant Frequency and Damping Analyser (RFDA) for density of solids.
A gamma density meter works by measuring the level of gamma radiation that passes through a material. This measurement is then used to determine the density of the material being scanned. The higher the density of the material, the more gamma radiation is absorbed, resulting in a lower reading on the meter.
divide the mass by the volume: mass/volume=density
To work out the density of an object, you need to know its mass (weight) and volume. Density is calculated by dividing the mass of the object by its volume.
Density is mass divided by volume.
Density x volume:)
The density of a potato is approximately 0.79 grams per cubic centimeter.
class width times frequency density gives you the frequency
you can't unless you have a set of weighing scales mass = density * volume density is needed to work out mass if you have volume if you worked out the mass then you could divide it by volume to get density
Hydrometers work by measuring the buoyancy of a liquid to determine its density. The hydrometer is a weighted glass tube with a scale inside. When placed in a liquid, the hydrometer floats at a certain level depending on the liquid's density. The scale on the hydrometer then indicates the density of the liquid based on where it is floating.
A hydrometer measures the density of liquids by floating in the liquid and sinking to a certain level based on the liquid's density. The higher the density of the liquid, the lower the hydrometer will sink. The scale on the hydrometer provides a reading of the liquid's density.
Frequency Density multiplied by the class width
Without knowing the substance, and thus its density, it is impossible to work out the weight in grams of the given volume in cubic decimetres. volume and mass are related by density: density = mass/volume → mass = density x volume.
If you don't know this you can work it out from the units: Density = kg/m^3 (kilograms per metre cubed) Mass is measured in kilograms Volume is measured in metres cubed You therefore need mass and volume to work out density.
