Salt

ive heard people using salt with mollies to prevent fin rot, is it safe to use with bettas, i dont mean brackish obviously.

just a tad. the box says a dosage of 0.1% will prevent fish getting disease, which is 1 tsp a gallon.

just wondered i dont want to do anything wrong

To be totally honest, if you water is of a good quality and you are doing regular water changes then you shouldn't need to use any preventative or cures. But to answer your exact question, I don't know but I am s re someone else will.

Mollies do better in brackish water - where some of the species that make up our aquarium hybrid mollies can be found in nature. In freshwater they are much more susceptible to fungus and other such ailments. To make the water mildly brackish you would be thinking of using marine aquarium salt, which would change the stats of the water to harder and more alkaline.

Aquarium salt isn't special, it's just sodium chloride, if you add it to the water I doubt it would have much effect on mollies (ignore what the packaging says, it's just trying to sell itself), or at least not nearly a much a positive affect as marine aquarium salt would have. Mollies can easily cope with it in the water though because brackish fish have an amazing ability to adapt their osmoregulatory system to cope with either salt or fresh water.

Regular freshwater fish - especially soft water species like bettas - cannot do this. Adding sodium chloride to the water is going to be making their osmoregulatory work overtime and could harm them in the long run. In the short run, it will make no real difference.
