74 Percent Concentration -The amount of solute dissolved in a fixed amount of solvent is called the concentration of the solution. Concentrations are typically expressed as Mass al.) (% m/m) which is the mass of the solute (g) divided by the mass of the solution [solute+ solvent] (g)x 1000/0; or as Volume ol.) (% v/v ) which is the volume of the solute in a fixed volume of solution (1O0mL of solution) x 1000/0; or less commonly in the laboratory,...
