Relative density, is also called specific gravity, and it is the ratio of the density (mass/volume) of a substance to the density of a particular reference substance, usually water. So, where density has the units of mass/volume, relative density (specific gravity) is unitless.
Nutrient dense food- is defined as the density of nutrients to kcalories. Nutrient dense foods provide more nutrients relative to kcalories.

Relative means" in relation to" or "compared to". Relative size describes how an object appears next to another object. Mt. Rushmore's relative size is huge compared to a mouse. But Rushmore's relative size is very small compared (relative) to the universe.
Total number of people divided by the total land area. also known as arithmetic density
the relation between relative density and density is that relative density of a substance is its density itself without its unit.
relative density methane
Relative density is determined by the ratio of the density of a substance to the density of a reference substance.
DENSITY : density is the ratio of mass and volume of the substance density=mass/volume RELATIVE DENSITY : It is the ratio of density of a substance to the density of water
DENSITY : density is the ratio of mass and volume of the substance density=mass/volume RELATIVE DENSITY : It is the ratio of density of a substance to the density of water
relative density is related to the density of water. i.e. a relative density of 19.3 means that it has a density 19.3 times the density of water. The density of water is 1g/ml therefore the density of gold is 19.3g/ml
In SI system, unit of density is kg/m3 But no unit for relative density as it is the ratio of density of the material to that of water
Relative Density = 1,5
Relative density
The ratio of thee density of a substance of the density of a standard , usually water for a liquid or solid and aur for a gas. The SI unit of relative density is g/ m3
The relative density of a substance is the ratio of its density to the density of some standard substance. The standard substance for solids and liquids is water. Thus for solids or liquids: Relative density = denisty of substance (kg/m3) / density of water (kg/m3) Relative density therefore has no units, it is a number, and indicates only how many times more dense the substance is than water. The relative density of water is 1 or 1000 kg/m3.
The relative density of a substance X, relative to a substance Y isDensity of X/Density of Y= (Mass of X/Volume of X) / (Mass of Y/Volume of Y)If Y is water then the relative density is called the specific gravity.
