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.
mass divided by volume
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.
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
Use a mass balance to find the mass then find the volume by V=mass/density.
density = mass/volume mass = density x volume
Volume = mass / density
You have to know two out of three ... mass, volume, density ... then you can find the missing one. If density is missing . . . Density = (mass)/(volume) If mass is missing . . . Mass = (density) x (volume) If volume is missing . . . Volume = (mass)/(density)
