1. A researcher mixed 5.00 ml of 2.03 x 10^-1 M Fe(NO3)3 with100.00mL of 2.05 x 10^-3 M KSCN, using 5.0 x 10^-1 M HNO3 assolvent for both solutions. The resulting measured absorbance forthe solution was 0.315. Based on the data what is [Fe*] (i thinkthis means the total Fe in solution)?

2. Ions B and C react to form BC. If 15.0 mL of 1.00M B is combinedwith 15.0 mL of 1.00M C, .00450 mol BC is formed. Determine the equilibrium constant.
