<p>My 5 steps to a 5 gives this equation: A = abc. However, I have no clue how to use any of these variables or how to find them. It has something to do with light absorption.</p>
<p>A is your absorbance, a is your molar absorptivity, b is the length that the light has to pass through, and c is your concentration.</p>
<p>All you have to know basically is that as you increase the concentration, the absorbance also increases.</p>
