Detailed explanation-1: -Thus, one mole of an element has a mass in grams equal to the atomic weight of that element and contains 6.02 X 1023 atoms of the element.
Detailed explanation-2: -1 mole contains 6.022 x 1023 entities (Avogadro’s number) Concept 1.
Detailed explanation-3: -However, other elements have different molar masses; for example, 6.02 x 1023 sulfur atoms have a mass together of 32.06 grams, which is sulfur’s molar mass.
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.
Detailed explanation-5: -We know that NA, Avogadro’s number, 6.022×1023 of sulfur atoms have a mass of 32.06⋅g precisely.
