Iron Crystal
Posted in Garden Antiques on 06/30/2010 11:42 am by adminCalculating the formula of iron 2 sulphate crystals?
A sample or iron (2) sulphate crystals has a mass of 11.58g. When heated until all the water has been driven off, the mass is reduced to 6.33g. Calculate the formula of the iron (2) sulphate crystals.
Much appreciated 
Well, if all of the water is driven off, wouldn't it just be iron II sulphate, meaning FeSO4?
