Sorry, ignore my previous question. I have realized that this whole confusion was mostly caused by one very stupid mistake that I should've seen. :redface:
But as for the values, thank you. They have been very useful.
Sorry, that misunderstanding may have been not providing enough detail on my part. Although I have already worked out the εmax to be at 0.0011 from my gradient of y=mx+c. As I am working out the end concentration of an unknown product, this has led to calculating my concentration to 632.72 from...
0.1 M HCl was added to the decresing volumes of Benzoic acid each time before being made up to 50cm3 with distilled water. Then, each of these sultions of differing volumes of benzoic acid were analysed in a spectrophotometer for absorbance values.
Hi guys! First time post here.
I was wondering where on the internet you could find such a value? I have tried searching for sites that may have a list of molar extinction coefficient values for various compounds but have found them to be quite hard to access. Would any of you with perhaps...
