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.
You would need to know the density of the object in order to calculate the volume from the mass. The formula to calculate volume from mass and density is: Volume = Mass / Density.
To calculate density, you need to know the mass of the object and its volume. Density is calculated by dividing the mass of the object by its volume.
I'm am sorry i do not know
Mineral density should know. Weight / density = volume
density = mass/volume mass = density x volume
To calculate the mass and volume of gold, we need to know either the mass or the volume specifically. Given the density of 19.3 g/cm3, if you have the volume of gold, you can calculate the mass by multiplying the volume by the density. If you know the mass, you can calculate the volume by dividing the mass by the density.
Density is mass per volume, so you need to know mass and volume.
You need to know the density of the material. Multiply the volume by the density will give you the mass
density = mass/volume If you know density and mass, you can calculate the volume by manipulating the density equation such that volume = mass/density. Example: density = 3.57g/cm3 mass = 2.4g volume = ? volume = mass/density = 2.4g/3.57g/cm3 = 0.67cm3
The best strategy in that situation would be to use what you do know.
Density depends on 2 things, mass and volume. If you don't know the volume you cannot calculate the density.
The formula to calculate the weight of brass is weight = volume x density. The density of brass varies depending on the composition, but a common value is around 8.4 g/cm^3. You would need to know the volume of the brass object in order to calculate its weight.
