SOLVED:A spectrophotometric method for the analysis of iron …

1. First, we need to determine the concentration of iron in the original 0.5 g sample. Since the iron ore is 40-60% w/w, we can assume an average of 50% w/w. So, in the 0.5 g sample, there would be 0.5 g * 0.5 = 0.25 g of iron. Step 2/7 2. Next, we need to convert the mass of iron to its concentration in the 1 L solution.
