This is the specific gravity of the mineral. It's a comparison of how much mass a given volume of it has compared to the mass of an equal volume of water.
It does not. It equals volume. The weight will vary depending on the substance occupying that volume.
volume and weight
Compare its weight to the weight of an equal volume of water. The weight of the specimen divided by the weight of the water equals the density of the specimen.
Height and diameter will give you the volume, if you know the density you can then calculate weight from that.
If the sample is homogeneous, then half of its volume has half of its mass and half of its weight.
Some properties of minerals that can be expressed in numbers include hardness (using the Mohs scale), specific gravity (a ratio of the mineral's weight to the weight of an equal volume of water), and refractive index (a measure of how light bends as it passes through the mineral).
Mineral density should know. Weight / density = volume
The density of a pure mineral is measured using various apparatus and techniques which are covered in most mineralogy textbooks.
Specific gravity
The weight of a mineral is compared to the weight of an equal volume of water using a measurement called specific gravity. Specific gravity is the ratio of the weight of the mineral to the weight of an equal volume of water. Minerals with a specific gravity greater than 1 are heavier than water, while those with a specific gravity less than 1 are lighter.
Percent of an objects mass is expressed in terms of its weight. Percent of an objects volume is expressed in terms of its size.
Specific gravity compares the weight of a mineral with the weight of an equal volume of water, while hardness measures a mineral's resistance to scratching or abrasion.
To find the volume of the mineral, you would first calculate the volume of the mineral using the formula: Volume = Mass / Specific Gravity. In this case, Volume = 2851.2g / 4.2 = 679 cubic centimeters.
The density of minerals is a measure of weight vs volume of the mineral. See related links for more details.
To find the specific gravity of a mineral, you would compare its weight to the weight of an equal volume of water. Divide the mineral's weight by the weight of the water, and you'll get the specific gravity of the mineral. This measurement can help identify the mineral and understand its composition.
Grams & milligrams measure weight, not volume. For measuring volume, use cubic centimeters or liters.
The mineral property you are referring to is density, which is the mass of a mineral per unit volume. It helps in identifying and distinguishing different minerals based on their weight or density.
