Suppose 5.0 mL of 0.0020 M Fe(NO 3 ) 3 dissolved in 0.50 M HNO 3 are mixed with 5.0 mL of 0.0020 M HSCN

Suppose 5.0 mL of 0.0020 M Fe(NO3)3 dissolved in 0.50 M HNO3 are mixed with 5.0 mL of 0.0020 M HSCN dissolved in 0.50 M HNO3, and the absorbance of the solution is measured to be 0.26. What is the equilibrium constant for the following reaction? Assume that the H+ concentration stays constant at 0.50 M. Round your answer to the ones place.

Fe3+(aq) + HSCN(aq) FeSCN2+(aq) + H+(aq)
