1. The problem statement, all variables and given/known data I made a graph of Absorbance vs. Concentration from data I got in the lab. I graphed it and now am trying to figure out how to find the slope of the curve. It's supposed to be a Beer's Law calibration curve. 2. Relevant equations 3. The attempt at a solution I used Excel and got y = 228.19x + .0369 as the trendline. Would 228.19 be the Beer's Law slope I need to use to find the concentrations of other absorbances later in the lab? It seems too high, but I really need feedback fast, please. Thank you.
