Homework Answers
For the first picture we can see that number of solute particle increases. So we have to add more solute.
For the 2nd picture and 3rd picture number of solute molecules decreases so we have to dilute the solution . so we have to add more solvent.

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,...
