Yes, but very slowly transition it from salt to fresh water. If possible place the fish in a tank of saltwater and each day do a very small water change in the tank replacing the saltwater with fresh. The first day just a cup or so, then slightly larger and larger water changes until it's all fresh. Take your time so that the fish can adjust as you go.

Yes and it doesn't take days.

I often move my mollies from fresh to salt especially when they are ready to have fry. I will move them to the salt water tanks.

You can use a bag and float them or a tupperware container. It doesn't take long since mollies like guppies are tolorant of changing from salt to brackish to fresh quite quickly.

Float the fish like you would from the store, in the container or bag. Begin adding tank water from your fresh water to your salt water. 1/2 cup at a time 15 - 20 minutes apart even a half hour. Repeat this process 6 times or so. If the bag or container becomes too full, pour the brackish water in the drain not in the tank. keep adding the fresh water

This will allow the mollies (which are hearty fish) to transfer to the fresh water PH which will be much lower than your salt tank.

I've done it a hundred times

Yes you can but all mollies require some salt, they are brackish water fish. Most of my mollies are in a freshwater tank with aquarium salt(1teaspoon for every 5 gallons), This process will take some time tho. You need to slowly acclimate them, adding 1/2 cup of freshwater every hour for at least 6 hours to the salt water. They will adjust to it! I have over 50 mollies(4 different types) and used them to cycle a saltwater tanks and then they went back to freshwater tank, it can be done. Mollies are hardy fish but will always require salt in their tank!

You want to kill it, Right...
Since it has gotten use to the salt water tropical tank and is healthy - Why do you want to make it ill and take it out of the tank it lives in. Buy more fish and put them in your non salt tropical tank...
Leave your molly alone.

Yes... The shock from salt to freshwater would probably kill it.
