CHEM 119: Fundamentals of Chemistry I

In this video, we delve into the concept of percent composition by mass, exemplified through the compound chloroform (CHCl?), which was once employed as an inhalation anesthetic despite its associated toxicity. By calculating the percent composition for each element within the compound, we gain valuable insights into its composition and its potential effects on health and properties.

We categorize elements into representative, transition, inner-transition, and noble gases based on their positions in the periodic table and general characteristics, without revealing specific element classifications.

Grasp the fundamental concept of moles in chemistry by equating it to the universally understood notion of a dozen. This video breaks down the usage of Avogadro's constant demonstrating calculations from moles to particles and vice versa. Using real-world examples like Carbon atoms Sulfur Dioxide molecules and Iron atoms viewers gain a clear understanding of moles and particle conversions
