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
The formula to find mass with density (ρ) and volume (V) is: mass = density × 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.
The formula for percent by volume (% v/v) is: (Volume of solute / Volume of solution) x 100 The formula for percent by mass (% w/w) is: (Mass of solute / Mass of solution) x 100
volume = Mass * density
Percentage change in volume= Change in volume/intial volume X 100
The formula for calculating mass is mass = density x volume. This formula relates the mass of an object to its density (amount of matter in a given volume) and volume (amount of space an object occupies).
Density is the amount of mass in a given volume of a substance. The formula for density is density = mass/volume.
(Mass) divided by (volume).
