The mass of an object is equal to the object's density multiplied by the volume (size)
mass (kg) = density (kg/m3) x volume (m3)
The mass of an object is equal to the object's density multiplied by the volume (size) mass (kg) = density (kg/m3) x volume (m3)
To calculate the surface area to volume ratio, simply divide the surface area of the object by its volume. This ratio is commonly used in science to understand how efficiently an object exchanges materials with its environment, with a higher ratio indicating better surface area for exchange relative to its volume.
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
Mass and volume.
Because volume is the ratio mass/density.
Surface area to volume ratio is defined as the amount of surface area per unit volume of either a single object or a collection of objects. The calculation of this measurement is important in figuring out the rate at which a chemical reaction will proceed.
Density is defined by an object's mass divided by it's volume.
The ratio of water vapor in a volume of air relative to how much water vapor that volume of air is capable of holding is called relative humidity. It is expressed as a percentage and provides insight into how close the air is to being saturated with water vapor.
That's the object's density.
Density is the ratio of an object's mass to its volume.
In physics, density is the ratio of an object's mass to its volume. Its SI units are kilograms per cubic meter (kg/m3).
You need to know the volume because the density is the ratio mass/volume.
