Question

explain the mole concept.plzz explain point wise not in a paragraph. good expaination needed

Answer 1

The mole is the amount of a substance of a system which contains as many elementary entities as there are atoms in 0.012 kilogram of carbon-12; its symbol is "mol." When the mole is used, the elementary entities must be specified and may be atoms, molecules, ions, electrons, other particles, or specified groups of such particles.

For example, one mole of oxygen gas (O 2 ) occupies a volume of 22.4 L at standard temperature and pressure (STP; 0°C and 1 atm), has a mass of 31.998 grams, and contains about 6.022 × 10 23 molecules of oxygen.

The mole is the unit of measurement in the International System of Units (SI) for amount of substance. 1 Mole is just a number whose value is equal to the Avagadro’s number i.e. 6.022 * 1023. So, when someone claims of a matter to be of 1 mole in quantity, that implies that the matter under consideration contains exactly 6.022 * 1023 number of particles (atoms, molecules, ions, electrons or any other elementary entities

Answer 2

Mole can be defined as a unit which represents 6.023 x1023 particles of same matter. A mole (symbol mol) is defined as the amount of substance that contains as many atoms, molecules, ions, electrons or any other elementary entities as there are carbon atoms in exactly 12 gm of .
