(adsbygoogle = window.adsbygoogle || []).push({}); 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.
