I. PURPOSE OF EXPERIMENT The purpose of this Lab is to use spectroscopy create graph to determine the concentration of dye in a sport drink‚ by creating series of standard dilutions of an FD&C Blue 1 Stock solution and measuring the percent transmittance of each dilutions. Results in each dilutions will be use‚ to determine the linear function among various functions (T‚ T%‚ log T‚ - logT) For a Beer’s law calibration curve. The produce provides a model for guided-inquiry analysis of the concentration

In test tube 1 with a 0% salt concentration‚ the potato core length after is 44 mm‚ the change in potato core length is 4 mm so the potato is hypertonic to that solution. In test tube 2 with a 0.625% salt concentration‚ the potato core length after is 42 mm‚ the change in potato length is 2 mm so the potato is hypertonic to that solution. In test tube 3 with a 1.25% salt concentration‚ the potato core length after is 39 mm‚ the change in potato length is -1 mm so the potato is

water concentration of a solution outside the cell is lower than the concentration inside the cell‚ water will move from the inside to the outside of the cell due to osmosis. As we increase the concentration of the NaCl solutions we have used (0.1M to 0.6M)‚ more moles of NaCl are dissolved in the solution. Thus‚ the solutions increases in solute concentration but decreases in water concentration. We can therefore assume; the higher the concentration of the NaCl solution‚ the higher the number of

Conquistador Beer Suggested Solution October 10‚ 2003 Approach to the Problem • Calculate a Demand Forecast for the Company. Then calculate Break Even Volume and compare them. • Demand Forecast = Industry Demand * Market Share for Conquistador Beer • BEV = Fixed Costs / (Price – Variable Costs) Calculation of Industry Demand • Method 1: Uses Tables A and B. Per capita beer consumption * population Population Per Capita Beer Consumption (gallons)** 33.1 gallons 49.6 gallons Industry

While a molar solution of acetic acid was prepared by the following computation: Density of acetic acid = 1.05; Purity of acetic acid = 99.9%; and Molarity of acetic acid = (Density x Purity x 1‚000) /(Molecular weight x 100) i.e.‚ M = (1.05x99.9 x 1‚000) / (99.9 x

molecules diffuse across the cell membrane from an area of higher solute concentration to an area of lower solute concentration. There are three relative concentrations of solutions. Hypertonic solutions yield a higher concentration than that of the cell.Hypotonic solutions have a lower concentration and isotonic solution has an equal concentration. Method: The eggs were soaked in vinegar for 48 hours. At the end of this period the eggs are dried off and mass is recorded. The eggs are then

A case study is a description of an actual administrative situation involving a decision to be made or a problem to be solved. It can be a real situation that actually happened just as described‚ or portions have been disguised for reasons of privacy. Most case studies are written in such a way that the reader takes the place of the manager whose responsibility is to make decisions to help solve the problem. In almost all case studies‚ a decision must be made‚ although that decision might be to

Oumou Fofana Period: 1 Mrs. Furlong December 19‚ 2012 Gummy Bear Lab Question- If the percent of the concentration of a solution varies‚ will the amount of water gained or lost vary in a linear fashion? Hypothesis- If the concentration of a solution varies‚ then the amount of water lost or gain will not vary in a linear fashion Prediction- I think that the amount of water lost will not vary in a linear fashion. I think the water will vary like one gummy bear would lose 4 grams while

The case study teaching method is appropriate for undergraduate‚ graduate‚ continuing legal training‚ executive education‚ and professional development courses‚ workshops‚ and seminars. Case studies are typically accompanied by teaching manuals or notes‚ which outline the basic premise of the case study‚ how it can be used within a course‚ learning objectives‚ assignment questions‚ a typical class discussion flow‚ and key takeaways. Teaching notes will often provide board plans‚ informational slides
