Do i need a chemical formula to calculate the mols of FeSO4*7H20 when given the mols of Fe(II)?

If so i only know that Fe(III) + H2SO4 + H3PO4 are the reactants, and FeSO4*H2O is the product. Help?

• chemical formula -

Ok, your first sentence is given the mols of Fe(II). Did you mean Fe(III) ? I assume so.

Balance the equation.

Fe + H2SO4+H3PO4>>FeSO4.7H20 + where did the phosphate go? Your reaction is incomplete

• chemical formula -

the mols for Fe(II) are the same as Fe(III) since the ratio is 1:1.

And that's the problem with the reaction. I don't know what else is made. I was just given those components. I'm assuming it would yeild FsSO4*7H2O + P? But i am unsure.

• chemical formula -

The only hint I was given was that I use the mols of Fe(II) to find the mols of FeSO4*7H20

I'm not surprised the answer was wrong. Chemical reactions are by mols and not by grams; therefore, 1 mol of each reactant produces 1 mol of each product but a mol is not a gram. SO, convert 0.5839 g KHC2O4 to mols, convert mols KHC2O4 …
