PPT-Dilutions

Stock solutions are concentrated we use water to dilute them to achieve the molarity desired for a solution Dilution the process of adding more solvent to a solution Decreases Remains constant. The following is a brief explanation of some ways of calculating dilutions that are common in biological science and often used at Quansys Biosciences Using C C To make a fixed amount of a dilute solution from a stock solution yo u can use the form 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. Mix 2 solutions together…. …they both get diluted.. It’s ping pong balls in a bucket…. 5 gallon bucket - Ping pong ball. 5 gallon empty bucket - 5 Ping pong ball. Add 1 gallon of water. What’s the “concentration of ping pong balls”?. 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. :. . Most . Probable Number Method (MPN). Most . Probable Number Method (MPN). What . is the MPN method?. How to determine the amount of bacteria from the MPN . method?. Objective. Most . Probable Number Method (MPN). Microbiologists have developed techniques for isolating and maintaining strains in the laboratory. Strains: microorganisms of the same species that are descended from a single cell and possess the same genotype. Introduction To Medical Technology. Lecture . - . 7 .

Solute: . substance dissolved in another substance (the solvent). Solvent: . substance that dissolves a solute, resulting in a solution. Add solvent. Remove solute. C. 1. V. 1. = C. 2. V. 2. C1 = initial concentration. V1 = volume of concentrated solution. C2 = final concentration . V2 = volume of diluted solution. Examples.

Jesus answered, “The most important is, ‘Hear, O Israel: The Lord our God, the Lord is one. And you shall love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.’ The second is this: ‘You shall love your neighbor as yourself.’ There is no other commandment greater than these.”.
