Is it just 3 fluoride to 1 manganese?
the bottle says Manganese (III) fluoride 99%
what does the 99% mean? Thanks

Yes

That's the purity - ie. the contents is 99% MnF₃, 1% other (you can check the suppliers website if you need info on what that might be)

Actually, to calculate the % of F in MnF3, don't you take the molar mass of F divided by the total molecular weight of MnF3?
about 50.92% F in MnF3 then?

That's fine if you wanted to find the % of F.

But :

the bottle says Manganese (III) fluoride 99%

It doesn't say 99% F.

So, as Dan said, it refers to the purity of MnF₃
