Mole Question

[generalkorn12]

Hey guys,

This is probably a stupid question, but why exactly can the mole of something be equal to exactly the mole of another?
eg. n(Na) = n(NaCl), the only reason I can think of is due to mole ratio.

The mole is simply a unit of measurement - think of it this way, a kilo of feathers and a kilo of bricks both weigh the same despite bricks being heavier because there's a kilo of both of them. A mol of Na and a mol of NaCl are the same thing because there's one mol of each of them.

Yes^^. Its the amount of something there is. Also, as you know, one mole has 6.023 . 10^23 particles. Regardless of weight, the amount of particles is the same for both.

I believe that is why we use the unit of the mole, due to convenience more than anything
