That is called density. The SI unit for density is kg/m3.
Density aka specific gravity is a measure of the amount of matter in a given volume. Actually specific gravity is not the measure of the amount of matter in a given value, it is a comparison of the density of the substance to water's density. Specific gravity is a unitless quantity.
The amount of matter in a given volume of space is its D-E-N-S-I-T-Y Its Density NOT Volume!
The concentration of solution is simply defined as the amount of solute present in a given amount (mass or volume) of solution, or the amount of solute dissolved in a given mass or volume of solvent. In other words, it is a term used to express how much of solute is dissolved in a particular quantity of solvent or solution. Hope this helps:)
Amount refers to the total quantity of a substance present, while concentration is a measure of how much of a substance is present in a given volume or mass of a solution. Amount is an absolute quantity, while concentration is a relative measure.
Density since ρ=m/v or in words; density is equal to the mass divided by the volume. i.e. amount of matter in a given space.
Density is the amount of matter in a given space.
This is the concentration.
The amount of matter in a given volume of space is called density.
The amount of mass, weight in a given volume.
Concentration of a solution refers to the amount of solute present in a given quantity of solvent or total solution. It can be expressed in various ways, such as mass/volume (g/mL), moles/volume (mol/L), or as a percentage. Concentration is important for determining the properties and behavior of a solution.
The amount of matter in a given volume is represented by the density of the substance. Density is a measure of mass per unit volume, typically expressed in units like grams per cubic centimeter. By multiplying the volume by the density of the substance, you can calculate the amount of matter present.
