WARNING!
Personally I'd toss it! Or put it down an ants nest...
From buying ACV for years I know that the "mother" sits on the bottom as in a sediment, and will intergrate throughout the vinegar when shaken...
If it floats I would venture to say that it has been opened at some stage and I just would not use it. I have never heard of mold in ACV, because it is a product that literally keeps for years without refrigeration... plus even if you removed the mold, spores would still be in the vinegar thereby making it unsuitable for internal or external use.
Stay safe and buy a fresh bottle...from another supplier.
