WebSep 5, 2024 · The mole is important because it allows chemists to work with the subatomic world with macro world units and amounts. Atoms, molecules and formula units are very small and very difficult to work with usually. However, the mole allows a chemist to work with amounts large enough to use. WebAug 15, 2024 · We can also state that 6 moles of sodium will require 3 moles of gas. If there are more than 3 moles of gas, some will remain as an excess reagent, and the sodium is a limiting reagent. It limits the amount of the product that can be formed. Chemical reactions with stoichiometric amounts of reactants have no limiting or excess reagents. northedge it training reviews https://heavenly-enterprises.com
