Students from Mr. Liecher’s grade 10 chemistry class discovered the relationship between grams, moles, and molecules during a recent science lab. The relationship between grams, moles, and molecules is a fundamental concept in chemistry and is governed by the mole concept. It allows chemists to connect the macroscopic world of mass to the microscopic world of atoms and molecules. We invite you to watch the video below as we eavesdrop on this lab.
