How To Use Moles - Part 2

The video tutorial explains how to calculate molecular mass by adding atomic masses of elements and multiplying by their occurrences. It covers the concept of moles, their role in chemical reactions, and how to calculate the number of moles from a given mass using molecular mass. Practical examples include calculating the molecular mass of sodium chloride and sodium iodide, and determining the mass needed for a specific number of moles of silicon dioxide. The tutorial emphasizes the importance of units and provides a method for rearranging equations to find unknown quantities.
