This activity is a brief, four-question warm-up, designed to be pre-lab questions for Gen Chem 1 students. Students were assigned these questions as homework before lab. This activity pairs well with a spectroscopy lab where students find the concentration of an unknown solution by making a calibration curve. The accompanying PhET simulation can be found here: https://phet.colorado.edu/en/simulation/beers-law-lab
