The mole is the unit of measurement for amount of substance in the International System of Units. Effective 20 May 2019, the mole is defined as the amount of a chemical substance that contains exactly 6.02214076×10²³ constitutive particles, e.g., atoms, molecules, ions or electrons.
The mole is the unit of measurement in the International System of units (SI) for amount of substance. It is defined as the amount of a chemical substance that contains as many elementary entities.For e.g. atoms.molecules,photons……
mole = 1 NA ( 1 NA= 6.022*10^23)
NA= Avogadro constant
It would be more clear if we take an example:
Calculate-
No. of Gram Atoms of N,
No. of Atoms of N,
No. of Moles of H Atom,
Given: 3 Moles of Urea Molecular Formula of Urea- NH₂ —CO—NH₂, 1 Molecule of Urea has 2atoms of N, 4atoms of H, 1atom of C, 1atom of O.
