Overview
Avogadro's Number is a fundamental concept in chemistry that allows scientists to count particles at the atomic level. It provides a bridge between the microscopic world of atoms and the macroscopic world we can measure. Understanding this number is crucial for performing calculations involving mole...
Key Terms
Example: One mole of water contains approximately 6.022 x 10²³ water molecules.
Example: Avogadro's Number allows chemists to convert between grams and moles.
Example: The molecular weight of water (H₂O) is about 18 g/mol.
Example: Stoichiometry helps determine how much product can be made from given reactants.
Example: In a combustion reaction, fuel reacts with oxygen to produce carbon dioxide and water.
Example: Boyle's Law states that pressure and volume are inversely related at constant temperature.
