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.
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 times volume isn't a formula for anything. You may be confused with mass divided by volume, which is the formula for density.
Volume = mass / Density Mass = Volume * Density Density = Mass / Volume
volume = Mass * density
mass= densityxvolume.

Mass / volume
Volume = mass / Density Mass = Volume * Density Density = Mass / Volume
Mass (M) x Volume (V) is not the formula for anything. Mass multiplied by Volume is the formula for density. Mass multiplied by velocity (speed with a direction) is the formula for momentum.
volume = Mass * density
Density rho = mass m / volume V. rho = m / V. Formula: Density equals mass divided by volume.
Percentage change in volume= Change in volume/intial volume X 100
mass = volume x density
(Mass) divided by (volume).
The formula of density is mass/volume. So mass divided by volume
mass= densityxvolume.
