I need help figuring out how to calculate (not even theanswer necessarily) the molar concentration of FeNCS2+ from ourexperimental data for runs 3 and 5. Than you
(10pts) A. Creating the Calibration Curve Calculate the molar concentration of FeNCS2+ in standard solutions 1-5, assuming that the reaction has gone to completion and that NaSCN is the limiting reactant in each case. Recall that the standard solutions were prepared according to Table KEQ.1. Table KEQ.1:Volumes for Standard Solutions Standard Solution Blank 1 2 3 4 5 0.200 M Fe(NO3)3 10.00 mL 10.00 mL 10.00 mL 10.00 mL 10.00 mL 10.00 mL Use your calculations to complete Report Table KEQ.3. Concentration of Fe(NO3)3 stock solution: Concentration of KSCN stock solution: 1.00x10-3 M NaSCN 0.00 mL 1.00 mL 2.00 mL 3.00 mL 4.00 mL 5.00 mL Report Table KEQ.3: Concentration and Absorbance of Standard Solutions 0.100 M HNO3 Dilute to 25.00 mL Dilute to 25.00 mL Dilute to 25.00 mL Dilute to 25.00 mL Dilute to 25.00 mL Dilute to 25.00 mL 2.00 × 10-¹ M 1.00 x 10-³ M
