Question

How many atoms/molecules are in a mole?

Answer 1

Basically, mole is an interesting topic in chemistry. Using mole concept, one can calculate the concentration of a solution.

mole(n) = (weight of the substance/molar mass of the substance)

Concentration = (n)/V ; where V is the volume.

In one mole of a substance, there are totally 6.023*10²³ atoms/molecules. This constant is called as Avagadro's number. If you multiply the no of moles with the avagadro number, you will get the total no of atoms/molecules.

1mole=6.023*10²³ atoms/molecules
