Light has mass but no volume. Although light particles called photons have energy and momentum which contribute to their mass, they are considered massless particles because they have zero rest mass and do not occupy physical space.
density is found by dividing mass by volume.................................
The mathematical relationship between mass 'm' and volume 'V' is that the ratio of these two quantities is equal to the density. The ratio of a substanceâ??s mass and volume is given as mass per unit volume. Density is a physical property of a substance.
The formula to calculate density is: Density = mass / volume. You simply divide the mass of an object by its volume to find its density. Density is a measure of how much mass is contained in a given volume.
To find the mass from volume and density, you can use the formula: mass = volume x density. Simply multiply the volume by the density value to calculate the mass. Make sure to use consistent units for volume and density for accurate results.
Mass and volume aren't interchangeable.
