Homework Statement
I have calculated the molar absorptivity of phenol, I'm pretty sure it's correct but I can't for the life of me figure out what I've done. Any help would be really appreciated.
Homework Equations
Beers Law:
A = εbc
Where A is absorbance, ε is the molar absorptivity, b is the path length the radiation traverses (1 cm) and c is the concentration of the compound in solution (mol L1).
The Attempt at a Solution
I have an absorbance of 0.0745. Then to get the number of moles I have done the following:
0.0283 and 10601 are constants as they appear throughout my calculations, but I have absolutely no idea where they have come from. Kicking myself for not keeping this in my lab book... lesson learned!
