Question

can anyone please explain me about mole concept I'm not getting it??​

Answer 1

See the mole concept mainly have the mole.

Now what is mole?

____________________

It is a mass of an atom , molecule or particles in GRAM.

Now how to calculate it?

_________________________

It is simply calculated by converting the atomic mass of each atom in the molecule(H2O) or a single element(He) in gram. For example if atomic mass is 23 u of an atom of the element then its 1 mole will be 23 g.

Now we know that every one mole of particles, atoms or molecules have 6.022×10^23 particles, atoms or molecule in it. It is called Avogadro Number and it is calculated scientifically.

IMPORTANT TO UNDERSTAND..

So u can say that 23 u is the mass of one atom BUT 23 g is the mass of 6.022×10^23 atoms!

Hope you understand......

Please ask doubts if u have any related to it.
