density = mass/volume
density = 15/20 = 3/4 units/ml
It's not exactly a "substance" but Density = Mass / Volume
If you want to CALCULATE the density of an unknown substance, you need to divide its mass by its volume, so you need to measure both first. If it is a homogeneous (uniform) substance, and you can take away a piece, you can take any sample. Any piece of the substance will have the same density.
The density is measured by dividing the mass of the substance with it's volume. Density = Mass/Volume.
Density is the ratio of the mass of a substance to the volume of the substance.
You can look up the density of different materials in a table of densities. But if you want a formula, just use the definition of density as mass / volume. This is also how you would measure the density of a substance of unknown density.
It's not exactly a "substance" but Density = Mass / Volume
divide mass and volume(:
All you can do with mass and volume is to determine the density of the substance. density = mass / volume or p=m/v after you determine the density, you can look on any density table and find the substance you are looking for. good look. -julio
Weigh it & measure its volume.
Density is the mass of a substance divided by the volume of that same mass of substance.
density = mass/volume = 43.54g / 26.5ml ≈ 1.643 g/ml
Density = Mass/Volume = 16.5 g / 2.2 cm3 = 7.5 g/cm3
When we divide the mass of a substance by its volume we get its density.
If you want to CALCULATE the density of an unknown substance, you need to divide its mass by its volume, so you need to measure both first. If it is a homogeneous (uniform) substance, and you can take away a piece, you can take any sample. Any piece of the substance will have the same density.
You can change the density of a substance by changing its volume. Density is equivalent to mass over volume. So changing the volume affects density.
If the density of the substance is known, then you can calculate it. Density = Mass/Volume, so Mass = Density x Volume
The density is measured by dividing the mass of the substance with it's volume. Density = Mass/Volume.
