Salts in Bitcoin wallet.dat hashes

Hello.
 
I also don't understand how HashCat can tell if a hash has salt or not.
 
Let's take the example of the password "ABCDE12345".
 
This string of characters will produce a hash X.
 
Just by the hash it is possible to know if the password is "ABCDE" and the salt "12345" or if "ABCDE12345" is really the whole password?
 
A greeting.
