Explanation / Answer

From your balanced equation: 1 mol FeSO4(NH4)2SO4.6H2O will produce 1mol FeC2O4 Molar mass FeSO4(NH4)2SO4.6H2O = 392.14 g/mol 4.0g = 4/392.14 = 0.0102 mol Theoretical production - 0.0102mol FeC2O4 Molar mass FeC2O4 = 143.86 g/mol 0.0102mol = 0.0102*143.86 = 1.46g Theoretical production of FeC2O4 = 1.46g
