Please help! Will rate.
You wish to measure the iron content of the well water on the new property you are about to buy. You prepare a reference standard Felt solution with a concentration of 5.23 x 10 * M. You treat 10.0 mL of this reference with HNO, and excess KSCN to form a red complex and dilute the reference to 50.0 mL. The diluted reference is placed in a cell with a 1.00-cm light path. You then take...

The standard curve was made by spectrophotographic analysis of equilibrated iron(III) thiocyanate solutions of known concentration. You are asked to analyze a Fe(SCN)2+ solution with an unknown concentration and an absorbance value of 0.104 . The slope-intercept form of the equation of the line is ?=4594.4?+0.0042 . The unknown was analyzed on the same instrument as the standard curve solutions at the same temperature. What is the Fe3+ concentration of the unknown solution?
