Question

why is mole in any molecules just one. why is it not more than one. pls elaborate.

Answer 1

see any element pr compou d has 6.022 × 1023 mole ules for co2has same no. of molecules i.e 6.022 × 1023 and the no. of c in co2is also 6.022× 1023

Answer 2

WHo said that it is only one?It can be more than one.Like there can be 1 moles of H2O,2 moles of H2O etc...Who said that it can only be one...?Now if you are referring to chemical formulae, then it is just to simplify calculations.
For example:
             N₂ + 3H₂ ⇒ 2NH₃
Here you can see that nitrogen molecule is one mole.The reaction will also take place even if nitrogen is 3,4 or 5 moles but you have to increase the moles of H₂ accordingly.

I believe that you got it.....
