How are concentration, molar absorption coefficient and absorbancy related?
How are concentration, molar absorption coefficient and absorbancy related, I haven't a clue and really need some help. This isn't for homework, I just can't remember and now it's bugging me!

The molar absorption coefficient is a constant for each compound and each wavelength of light. The relationship between all of these is called Beer's Law:
A = ebc
where A = absorbancy, e is the molar absorption coefficient and c is the concentration. b in the equation is the thickness of a solution, and is usually 1 cm.
