The density is the mass per volume; so that 171.2 g/8.0 cm3 = 21.4 g/cm3. The specific gravity is the density of the substance divided by the density of water at its greatest density (21.4 g/cm3)/(1 g/cm3) = 21.4
NOTE: While density gas units of g/cm3, specific gravity has no units as they cancel out in the previous equation

What is the specific gravity of platinum in pounds?
Specific Gravity is unitless. To determine the specific gravity of something you take the density of the substance divided by the density of water (assuming both densities are in the same units ie: g/cm^3, or lb/in^3So for platinum, whose density is 21.45grams/cm^3 you would take (21.45g/cm^3)/(1g/cm^3(this is the density of water)), so specific gravity=21.45This would be the same answer is you had your densities in terms of lbs.
Is density the same thing as specific gravity?
Almost, but not quite. 'Specific gravity' is the density of a substancecompared to water.Numerically . . .Specific gravity of a substance = Density of the substance/Density of water.
What is the relationship between density and specific gravity?
There is a very great relationship between density and specific gravity. Density contributes to the weight of a substance under specific gravity.
Is specific gravity the same as density?
More or less. Specific gravity is the density of a substance, compared to the density of water - so the units may vary.
What is the relationship between the density of a substance and its specific gravity?
Specific gravity is the density of a substance, compared to (divided by) the density of a reference substance, usually water.

What test is used to determine a mineral based on its density in comparison to the density of water?
specific gravity test
What is the purpose of conducting specific gravity test?
Specific gravity refers to the ratio of the density of a substance to the density of a reference substance. The purpose conducting specific gravity test is to determine if the test fluid will be heavier or lighter than the standard fluid.
How do you measure specific gravity of sand?
Determine the density of the sand. Determine the mass of the sand, and it's volume. Divide the mass by the volume and that gives you density. Then divide the sand's density by the density of water. That will give you the specific gravity of the sand. Because you divide densities, the units cancel out, and specific gravity does not have any units. For example, you determine the density of the sand to be 10g/cm3, and the density of pure water is known to be 1g/cm3. Divide 10g/cm3 by 1g/cm3. The g/cm3 cancel, and you are left with just the number 10. So in this example the specific gravity of sand is 10.

How did early prospectors use density to determine whether they had found gold or pyrite?
Specific gravity.
The property which compares the density of a substance with that of water is known as its?
"Specific gravity" or "specific density"
What is the relationship between density and specific gravity?
There is a very great relationship between density and specific gravity. Density contributes to the weight of a substance under specific gravity.
How to determine specific gravity of oils?
The term specific gravity means density in comparison to that of water. Density is weight divided by volume. So to get the volume, pour the oil into a graduated cylinder or measuring cup (same principle). To get the weight, use a scale (a chemist would use a triple beam balance). Once you have the density you can divide it by the density of water, and the result is the specific gravity.
Specific is the ratio of an object's density to that of water?
Specific Gravity.
When the specific gravity equal to density?
Specific gravity and density will have the same value when the two substances under investigation have identical densities. Density is an expression of the amount of mass per unit of volume that a substance exhibits. Specific gravity is a comparison of the density of a substance to the density of water.
What is the relative gravity on earth?
"Relative gravity" is used more or less as a synonym for density; it bears no direct relation with "gravity" as such. So, you would have to specify, "specific gravity [or density] of what substance"."Relative gravity" is used more or less as a synonym for density; it bears no direct relation with "gravity" as such.
