density
Percentage by Mass = Mass of substance of interest/Total Mass Percentage by Volume = Volume of substance of interest/Total Volume Converting from one to the other requires information about their relative densities.
A percentage is a pure, dimensionless number. It has neither length, nor area, volume, mass, temperature or any other dimension.
The percentages refer to the amount of a substance of interest that is contained in a compound or mixture of that and other substances. Percentage by mass = 100*mass of substance of interest/total mass. Percentage by volume = 100*volume of substance of interest/volume mass. And, incidentally, the word is definition, not diffinition.
Multiply them: density*volume = mass
No mass divided by volume

Find the volume then divide the mass by the volume.
You have to find out its mass, and its volume. Then you divide its mass by its volume.
To find the volume of mercury, you need to know the density and the mass of the sample. Once you have the mass, you can use the formula: volume = mass/density to calculate the volume of mercury.
Find its volume. Divide the mass by the volume to get the density.
Density = Mass / Volume Rearranging this gives: Volume = Mass / Density Mass = Density × Volume
mass = density ( )/cm3 multiplied by volume( )cm3
You can find the mass of a substance by using the formula mass = density x volume. Multiply the density of the substance by its volume to calculate the mass.
Volume = mass / density
density = mass/volume mass = density x volume
