You have been asked to determine the empirical formula of an iron(?) nitrate salt, Fe(NO). You weigh out 4.1419 g of a solid iron(?) nitrate sample and dissolve it with DI-HO while filling to the calibration mark of a 250.00 mL volumetric flask. You then use an ion-selective electrode to determine the iron ion concentration, which gives a reading of 3910 mg Fe^?+/L . Calculate the empirical formula of your iron(?) nitrate sample. (Hint-Assume that the remaining percent of ions in solution are nitrate ions.)

Calculate the empirical formula of your iron(?) nitrate sample. (Hint-Assume that the remaining percent of ions in solution are nitrate ions.)
Expert Solution
Step 1
Firat we would calculate the mass of iron and nitrate ion . Using the mass , we would calculate their moles.
From moles we would determine their mole ratio to calculate the empirical formula.
