Mole concept
𝗜𝗻𝘁𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝗼𝗻 𝘁𝗼 𝘁𝗵𝗲 𝗠𝗼𝗹𝗲 𝗖𝗼𝗻𝗰𝗲𝗽𝘁 ● The mole concept is a fundamental principle in chemistry that helps us quantify and understand the world of atoms and molecules. ➜ Defining the Mole: ● The mole (mol) is a unit of measurement used to count entities on the atomic and molecular scale. ● 1 mole contains Avogadro's number of entities, which is approximately 6.022 × 10²³ particles. ➜ Avogadro's Number: ● Avogadro's number (6.022 × 10²³) is the number of atoms, molecules, or ions in one mole of a substance. ● It provides a bridge between macroscopic and microscopic scales, allowing us to relate mass and number of particles. ➜ Molar Mass: ● Molar mass is the mass of one mole of a substance, expressed in grams per mole (g/mol). ● For elements, molar mass is numerically equal to the atomic mass in atomic mass units (amu). ● For compounds, molar mass is calculated by adding the atomic masses of all atoms in a molecule. ➜ Conversions Using the Mol...
