38) SEP Develop a Model Imagine you have a box and a set of red and green balls. The red balls represent solute particles, and the green balls represent solvent
particles. Sketch a model showing how the number of red balls doesn't change as
more green balls are added. Use your model to show how the percent by count of
red balls to total balls decreases.
