how to calculate concentration? chromatography « on: May 16, 2022, 08:45:44 AM » Hi All,I am having a hard time figuring out how to calculate a concentration based on a measurement on a liquid chromatograph.If I start with 1.487 g of a sample and dillute it in 20 ml of etha...
Equilibrium constants for ionization reactions are calls acid dissociation constants (Ka). Stronger acids have a higher Kawhile weaker acids have a lower Ka. Now, just as with hydrogen ion concentration, where you made the switch to pH instead of just H, scientists use pKato indicate how stron...
Molarityis one of the most common units of concentration. It is used when the temperature of an experiment won't change. It's one of the easiest units to calculate. You get the mass of solute for the solution, mix the solute with a known volume of solvent, and divide mass by volume ...
then calculate x. You can use the spreadsheet program to do this calculation for you and make it quicker. You have now calculated the concentration of the chemical of interest in three of your diluted unknowns. The original solution was diluted to prepare these unknowns, however...
Re: How to calculate concentration using chromatograph peak area «Reply #1 on:October 06, 2012, 06:30:09 PM » Yes, you will have to have an area for a standard: that's a sample of pure caffeine of known concentration. Can you look at all the data you've been given to begin ...
