Six iron tablets containing FESO-7H,0 were dissolved in 100-ml of 0.1 M HNO; with gentle heating All of the Fe strong oxidizing conditions. After the solution had cooled to room temperature 2.5-ml of 35wt% NH4OH was added The precipitate Fe;0-xH,0 15 convertca that was filtered weighed 0.345 g. Thermogravimetric analysis of the crude product showed a 10.5% weight loss below 150 C. How much iron was in each of the tablets? Report the average mg-Fe per tablet?
