That is called "density".
Ye.. the concentration of a substance is measured as the amount of substance per unit volume. Accordingly, the amount of a substance in per unit volume is the concentration of the substance.
That is called the density of the substance.
volume
The amount of substance in a given unit of volume is called concentration. It is typically expressed as the number of moles of a substance per unit volume, such as mol/L (molarity) or mol/cm³.
The amount of mass, weight in a given volume.
The amount of a material in a given space is its density. Density is defined as the mass of a substance per unit volume and is a measure of how tightly packed the atoms and molecules of a substance are in a given volume.
The amount of substance in a given volume is represented by the concentration of the substance. It is typically measured in units such as moles per liter (mol/L) for liquids or gases. This concentration value indicates how much of the substance is present in a specific volume of the 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.
The amount of mass in a given volume of a substance is known as its density. Density is calculated by dividing the mass of the substance by its volume. It is expressed in units such as grams per cubic centimeter (g/cm^3) or kilograms per liter (kg/L).
The amount of substance per unit volume or the number of moles of a substance per unit volume is called its MolarityI think you meant to say "What is the MASS of substance in a given volume called?", meaning what name is given to the mass-per-unit-volume of a substance, i.e. the mass of a chunk of it divided by its volume. The is density.
It varies from substance to substance and salt to salt.
The relationship between volume and mass in a substance is determined by its density. Density is the amount of mass per unit volume of a substance. In general, if the density of a substance is high, then its mass will be high for a given volume, and vice versa. This means that as the volume of a substance increases, its mass may also increase if the density remains constant.
