Mass divided by the specific gravity will give you the volume, since sp. gr. tells you how much space (volume) a unit of the substance occupies.
For instance, if you have 2 grams of water, and you know its sp. gr. is 1g per cc (cubic centimeter) - which you can find from specific gravity tables - then you know that 2 grams will occupy 2 cubic centimeters.
Mass times volume isn't a formula for anything. You may be confused with mass divided by volume, which is the formula for density.
Mass / volume
Density rho = mass m / volume V. rho = m / V. Formula: Density equals mass divided by 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
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).
The amount of mass, weight in a given volume.
(Mass) divided by (volume).
mass = volume x density
mass= densityxvolume.
