PPT-9.5 Dilution of Solutions

In a dilution a solvent usually water is added to a solution which increases its volume and decreases the concentration of the solution Making orange juice from concentrate is an example of a dilution . An introduction to dilutions. Dilutions are fractions. When we add water to orange juice concentrate to make orange juice for breakfast, . we are making a dilution. .. The dilution that we have made can be determined by the expression:. An Introduction. Activity overview. In this activity you will visualize what is meant by a ‘dilution’.. You will also examine how to express the dilution that has been made.. Part I: Dilutions made with food coloring. Solution Preparation. How do we create chemical solutions in a laboratory setting with a certain concentration/molarity? . Obtain the mass of the chemical compound serving as solute. Dissolve the solute in a small amount of the solvent. Saccharomyces. . cerevisiae. Kasey O’Connor. Ashley Rhoades. Department of Mathematics. Loyola Marymount University. BIOL 398-03/MATH 388.
