Homework Help: Beer's Law and Graph

  1. Dec 14, 2014 #1
    1. The problem statement, all variables and given/known data
    I am given a linear graph that is Absorbance vs. Concentration. How do I find epsilon in the beer's law equation?

    2. Relevant equations
    Beer's law: A = Epsilon x L x c

    3. The attempt at a solution
    I just need a general explanation. Thanks.

    Gee. Let me think. What do those symbols and letters mean/stand for?

    A = εbc ⇔ y = mx + b

    Hint 2: Because the b term (y-intercept) throws many off. What would the absorbance be if C = 0?
