Question

write short note on mole concept​

Answer 1

Answer:

HEYA HERE IS YOUR ANSWER:

Explanation:

MOLE CONCEPT:- a mole of a substance is that amount of the substance which contains the same number of entities(atoms,molecules,ions,electrons,photons etc.) as there are atoms in exactly 12 grams of pure carbon-12.

one mole is a collection of 6.022 × 10^23 particles.

Molar volume- one mole of any gaseous substance occupies a volume of 22.4 litres.

Answer 2

Answer:

The mole (symbol: mol) is the unit of measurement for amount of substance in the International System of Units (SI). A mole of a substance or a mole of particles is defined as exactly 6.02214076×1023 particles, which may be atoms, molecules, ions, or electrons.

Explanation:

he mole (symbol: mol) is the unit of measurement for amount of substance in the International System of Units (SI). A mole of a substance[1] or a mole of particles[2] is defined as exactly 6.02214076×1023 particles, which may be atoms, molecules, ions, or electrons.[1] In short, for particles 1 mol = 6.02214076×1023.[3][2]

The current definition was adopted in November 2018 as one of the seven SI base units,[1] revising the previous definition that specified it as the number of atoms in 12 grams of carbon-12 (12C), an isotope of carbon.

The number 6.02214076×1023 (the Avogadro number) was chosen so that the mass of one mole of a chemical compound in grams is numerically equal, for most practical purposes, to the average mass of one molecule of the compound in daltons. Thus, for example, one mole of water contains 6.02214076×1023 molecules, whose total mass is about 18.015 grams – and the mean mass of one molecule of water is about 18.015 daltons.
