Hi!
I don't really understand why mole is a SIunit. I mean, it's just a number, it has no dimension.
Edit: I meant "unit", not "enhet" (which is the Swedish word for unit (temporary confusion))

Imagine a length, right? it has 2 dimensions, length and amount.Originally Posted by thyristor
Amount is a dimension see?
I'm afraid I don't quite see what you mean.Originally Posted by LeavingQuietly
Imagine that you had 0 lengths. Why, that has 0 dimensions.Originally Posted by thyristor
So why did the length loose 2 dimensions when it just lost an amount?
Imagine now that you decreased the length to 0. how many dimensions are there now?
1, since the amount of the 0 long length is still one.
Need to discuss this more?
because there is a difference between a grammole and a kilogrammole, for instanceOriginally Posted by thyristor
It is not just a number. Avagadro's number is a number.
