A student mixed 4.00 mL of 1.02 x 10-1 M Fe(O3)3 with 100.0 mL of 1.98 x 10-4 M KSCN using 5.0 x 10-1 M HNO3 as the solvent for both solutions and found the absorbance of the resulting equilibrium mixture to be 0.235. Given these data, calculate the K value (The e value for Fe(SCN)2+ is 4700 L mole-1cm-1 and b = 1 cm)

I got: [Fe^3+] = 3.87 x 10^-3 M

[SCN^-] = 1.40 x 10^-4 M

[Fe(SCN)^2+] = 5.00 x 10^-5 M

Please show your work if you are able. Thank you in advance. :)
