Analysis of Co?by Spectrophotometry 3. Utilizing the data below to calculate the absorbances of your dilutions from part 2 % Transmittance This exam involves using best practices to analyze a Counknown solution. Multiple working standard solutions will be prepared bydiluting a stock solution of Cocle The 0.200M stock solution will be the highest concentration standard it has been analyzed to give the table (below) of absorbances as a function of wavelength. This analysis will be done by spectrophotometry. Measurements are...

Beer's Law Calculations: A. Dilution Calculations 1. Use the actual mass of cobalt(II) nitrate hexahydrate you used to calculate the concentration of your stock solution. 2. Calculate the concentration of your diluted solutions. The easiest way to do this is with the equation MiV2-M2V2. Show the work for the calculation of the concentration of at least one of your dilute solutions. 3. Make a table...

Hi
I am im a biochemistry lab and we are doing an experiment titled:
PCR Amplification of LeuRS F C Terminal Domain. I am having
troubles figuring out the rest of my caluclations.
I already did the calculations for the first dilution set, I
was wondering how I would do the calculation for the second
dilution set.
Also I was wondering how I would determine the theoretical
values for my data. Is there a specific formula I can use?
