Mole Concept Overview
The mole is a huge part of stoichiometry. In chemistry the mole, or Avogadro's number, is a fundamental unit in the SI system. That number is 6.02 x 10^23. A mole is the quantity of anything that has the same number of particles found in 12.000 grams of carbon-12. The special property of a mole is that one mole of an element contains the same number of atoms as a mole of any other element. Moles give us a consistent method to convert between atoms/molecules and grams. One mole of anything equals 6.02 x 10^23.
- Mass of one mole of the given substance
- Calculated by dividing the experimental yield by the theoretical yield
- Percentage by mass of each element in a compound
- A formula giving the proportions of the elements present in the compounds but not the actual numbers or arrangement of the atoms
- Reduced form of the molecular formula
- A chemical formula based on analysis and molecular weight
- Description of the quantitative relationships among substances as they participate in chemical reactions
- The reactant in a chemical reaction that determines the amount of product produced
