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...

5. The following data were obtained when Bio 106 students created solutions of the following concentrations (column 1), These students then placed three different samples of each concentration in a spectrophotometer and measured the absorbance. The following data table was created by these students. Create a standard curve from the data in the following table. Be sure to calculate the average absorbance for each concentration (round to two decimal places). After you have created the table, answer the following questions....
