stads_29 Posted October 5, 2009 Share Posted October 5, 2009 The p-nitrophenolate ion absorbs lights at 405nm. A solution that is 74um in the p-nitrophenolate ion was diluted 1 in 2 with water.Absorbance of resulting solution at 405nm was .650. Calculate molar extinction coefficient of the p-nitrophenolate ion at 405nm. Your meant to assume water has no absorbance at 405 nm. How do you use the beer lambert law to predict the absorbance at 405nm of a solution that is 11.0mM in the p-nitrophenolate ion, how do you show absorbance has no units?

CharonY Posted October 5, 2009 Share Posted October 5, 2009 Should be in homework. Why not just write down the Lambert-Beer law and start plug in the numbers. Or ask if there is confusion to what is what. Link to comment Share on other sites More sharing options...
