Detailed explanation-1: -One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro’s number or Avogadro’s constant. The concept of the mole can be used to convert between mass and number of particles.. Created by Sal Khan.
Detailed explanation-2: -WHAT’S A MOLE? Avogadro’s Number is the number of atoms, molecules, or other objects that makes up one mole of a substance. For example: 6.022 x 1023 hydrogen atoms represent one mole of hydrogen.
Detailed explanation-3: -The definition of Avogadro’s number of 6.022 × 1023/mole is the number of atoms or molecules per one gram atomic weight. For one gram atomic weight of hydrogen with atomic weight of one gram, one mole of hydrogen contains 6.022 × 1023 hydrogen atoms.
Detailed explanation-4: -A mole is defined as the number of atoms in 12 grams of Carbon-12. The number of atoms or molecules in a mole is known as Avogadro’s number, and is equal to 6.022 x 1023. A mole is the SI unit for amount of a pure substance.
