Number and Weight Average Molecular Weight Example | Polymer Engineering

In this video we go through an example finding the number average molecular weight and the weight average molecular weight of a polymer sample. The number-average molecular weight is the mean polymer chain length molecular weight, whereas the weight-average molecular weight is the average molecular weight when the weight of each polymer is accounted for. This timeline is meant to help you better understand how to find the number-average and weight-average molecular weight of a polymer sample: 0:00 Introduction. 0:46 Finding the Number-Average molecular weight 2:07 Finding the Weight-Average molecular weight 3:33 Outro Follow & Support StudySession: https://www.patreon.com/studysessionyt http://www.studysession.ca Email Us: [email protected] https://teespring.com/stores/studysession https://twitter.com/StudySessionYT https://instagram.com/StudySessionyt/ This video is part of our polymer engineering course. Polymer engineering is the study of polymers. In particular the study of polymers different properties and characteristics. In this playlist we will learn everything from the fundamentals of polymers to a more complex understanding of how polymers are derived and characterized. #studysession #polymers #polymerengineering
