Chad provides a brief yet succinct lesson on the various units in which concentration is measured. A comparison of molarity, molality, mole fraction, mass percent, parts per million (ppm), and parts per billion (ppb) is presented. It is also demonstrated how to convert mass percent to molarity, molality, and mole fraction.

I've embedded this playlist as a course on my website with all the lessons organized by chapter in a collapsible menu and much of the content from the study guide included on the page. Check this lesson out at https://www.chadsprep.com/chadsgener...
