- Let's pretend your little cousin walked in on you as you were performing your experiment. They took your dyed liquid and made their own sample by diluting it with water just as you did. However you did not see how much water they added. Assume the graph below represents your measured results. Now lets say you take one more image using your little cousin's sample of unknown concentration, and you calculate the absorption value to be 0.34. What is the approximate concentration of the solution that your little cousin mixed?d ← Chrome esc e 24% (92) ALE X Mathwa X G 102 cels X ☆ www-awu.aleks.com/alekscgi/x/isl.exe/1o_u-IgNsikr7j8P3jH-IvTqeviKFP6W0cqJcWJdIACROQwyw24GWHinMCnqLGstAPM iZtogOAPGJIWPnLIY... 17.4 Solubility and... 18.3 Gibbs Free E... 5.3 Enthalpies of... 18.5 Gibbs Free E...
