A two tablet sample of a vitamin/mineral supplement weighting 6.08 g was wet ashed to eliminate organic mattter, complexed with a highly colored ligan and then diluted to 1.00L volume. two 10.00 ml aliquots were then analyzed. calculate the average wight of iron in each tablet, based on the following information:

Fe(III) , 1.00 ppm LIgand H2O Absorbance
0 ml 25 ml 15 ml 0.492
15 ml 25 ml 0 ml 0.571
