Regarding concentration units (entry for a prize)

What does concentration (W/W) mean? What does (W/V) mean? What does a concentration of 100% (W/V) mean? Please ask some experts for help!
Mass percent concentration of solute (w/w) = Mass of solute / Mass of solution. Mass concentration of solute per unit volume (w/v) = Mass of solute / Volume of solution
Hehe, can someone give a specific explanation? What does (W/V) mean? Does 100% mean that the material is saturated?
w/w is the mass percentage concentration, that is, the number of grams of solute contained in 100 milligrams of solution； w/v is the mass-volume percentage concentration, that is, the number of grams of solute contained in 100 milliliters of solution. 100% (W/V) means 100 grams of solute with an appropriate amount of solvent to make up 100 milliliters, and it does not imply that the mixture is saturated.
Mass percent concentration of solute (w/w) = Mass of solute / Mass of solution. Mass concentration of solute per unit volume (w/v) = Mass of solute / Volume of solution
W/V refers to the mass content of solute per unit volume.
In concentration units, W represents mass and V represents volume. The formulas are as follows: Mass percent concentration of the solute (w/w) = Mass of solute / Mass of solution. Mass concentration per unit volume of the solute (w/v) = Mass of solute / Volume of solution. 100% does not necessarily mean that the substance is saturated; this depends on the substance in question and its saturation vapor pressure.
