Think I know the answer, but my stock pot of iron II sulphate is labelled as Fe2SO4.7H2O, with a mol.wt 278, I am presuming the extra 2 in the formula is their misprint???
Would have put this in chemistry thread, but its for making up algae medium, so cross subjects...

Some of them annoyingly replace the roman numerals with the alpha numeric which is patently wrong :(

As long as the Mr is the same I'd assume it's the right stuff with a "2" instead of a "II"
 
Seems to be, yes. Doing a CTRL+F to seach for Fe2SO4 in the hazcard pdf returns no matches, and typing in the full formula into Google, Google autocorrects the results to the expected formula, so the 2 seems erroneous.
