Chemistry Lessons: Molar Mass - with 5 examples
Finding the molar mass of a compound is often the first step in more complicated chemistry problems. When we say "molar mass," we mean the mass of 1 mole of that compound. Sometimes it's called the Gram molecular mass . We'll also explain what is meant by gram formula mass. That's a lot of terms that all sort of mean the same thing - so it's no wonder people get confused. We'll work through 5 examples.

About our instructor:
Kimberly Hatch Harrison received degrees in Biology and English Literature from Caltech before working in pharmaceuticals research, developing drugs for autoimmune disorders. She continued her studies in Molecular Biology (focusing on Immunology and Neurobiology) at Princeton University, where she began teaching as a graduate student. Her success in teaching convinced her to leave the glamorous world of biology research and turn to teaching full-time, accepting a position at an exclusive prep school, where she taught biology and chemistry for eight years. Kimberly co-founded Socratica Studios.
