This video outlines the process of calculating the number of moles in various elemental samples. It begins by explaining the relationship between molar mass and atomic weight. Each sample's mass is divided by the respective element's molar mass to find the number of moles. It provides detailed calculations for four elemental samples: zinc (Zn), argon (Ar), tantalum (Ta), and lithium (Li), converting results to scientific notation where necessary. The script demonstrates how to determine the mole
