A mole is simply a description of how many of something there is present. There are 6.022 x1023 "things" in a mole (similar to a dozen...a dozen is 12 of something). The number 6.022 x1023 is called Avogadro's number
The mole is one of the most useful concepts in chemistry.it is important to prcticeusing it,and relatedtermes,to be abel to quickly say that the number particles that are in amol of the subestanceand how mach this number of particlesweighs.
n=m/M where nis numberof mol,m=givenmassand
M=Molarmass.
The mole basically means 6.022 x 10^23 entities(ions,atoms,molecules etc)
It can be compared to the dozen(12 of something) , score ( 20 of something) etc.
But it differs from them in the sense that the mass of a mole of something (mentioned above) is fixed - the molar mass - which is the relative Atomic Mass,molecular mass,or ionic mass in GRAMS.
Also the volume of a mole is also a constant i.e 22.** litres.
A mole is practically a pile of atoms, molecules or ions. Think of it as a collective noun of these entities. Since finding the mass of one single entity is difficult, scientists measure the mass of a pile of these entities.
1 mole=6.022 X 10^23 entities.
A mole is a specific number of particles, which is Avogadro's Number, approximately 6.02 x 1023. The particles in question are either atoms or molecules.
Infact not 'moral concept' but 'mole concept' are studied in chemistry.
mole concept is used in balancing chemical reaction because for balancing a reaction u cant change the numbers such as 1,2,3 etc.. in between the compund so as a whole we are changing outside the compound
Avogadro discovered the number of atoms in a mole, but scientists like Wilhelm Ostwald, Stanislao Canizzarro, and Johann Josef Loschmidt also contributed to the theory.
a mole of subatomic particles, e.g. electrons, protons, neutrons, neutrinos, alpha particlesa mole of atoms of a monatomic element, e.g. carbon, helium, sulphur, gold, plutoniuma mole of molecules of a polyatomic element, e.g. hydrogen, nitrogen, oxygen, ozone, chlorine, iodine, triiodide iona mole of molecules of a compound, e.g. water, carbon dioxide, sodium chloride, vitamin D3, PVC, nitroglycerine, TNTa mole of massive objects, e.g. sand grains, eggs, donuts, bricks, basketballs, bowling ballsIn all cases a mole is the same number of objects (6.02214129E23), regardless of the type, size, or mass of the objects. The mole is analogous in concept to other named unitless quantities, e.g. a dozen (12), a gross (144).
No. The mole of solution is equal to mole of solute plus mole of solvent (solVENT !, not solution)
One mole is a quantity used to describe a group containing its 6.022 x 1023 particles.For example :-Substance quantity mass(g)carbon one mole 6oxygen one mole 16nitrogen one mole 14Hydrogen one mole 1silver one mole 108sodium chloride one mole 58.5
A mole is a quantity of substance which has Avogadro's number of molecules or atoms in it.
Atoms and molecules are very small and the mole concept allows us to count atoms and molecules by weighing macroscopic amounts of material.

i did you alien! i did! mother hen bay girl!

You use mole ratios for two reasons. One: To balance the number of moles to get the correct answer. Two: To finalize the cancellations of the measurements to get the answer.
Amedeo Avogadro. "Avogadro's number" is named for him, though it was done posthumously.
This question is solved with the help of mole concept . 1 mole of anhydrous calcium carbonate weighs 40+12+48=100 gm . 1.25 mole of similar anhydrous calcium carbonate will be 100* 1.25 = 125 gm
