When we record the amount of mass in a volume of water we are measuring the density of sea water.
The density of seawater
Step-by-step explanation:
Density is defined as the amount of mass contained in unit volume of water. It is given by the equation D=mass/volume
The unit of the physical quantity density is
.
Density is crucial in determining buoyancy. Buoyant force exerted by a denser liquid will be greater than the buoyant force exerted by a less denser liquid. Relative density is a dimensionless quantity that helps in understanding the density of a liquid by comparing it with a standard density.
Relative density of a liquid is the ratio of density of the liquid to the density of water which is taken as the standard.
