A student mixed 5.00 mL of 0.100 M Fe(NO3)3 with 50.00 mL of 2.00x10−4 M KSCN. The student measured the absorbance of one aliquot of the solution at a wavelength of 447 nm, with a pathlength of 1.00 cm. The absorbance reading was 0.615. Compute the following quantities a. [FeSCN2+]eq = b. (mols FeSCN2+)eq = c. (mols Fe3+)initial = d. (mols SCN−)initial = e. (mols Fe3+)eq = f. (mols SCN−)eq = g. [Fe3+]eq = h. [SCN−]eq = i. Keq=

A standard 3 mL cuvette is two-thirds filled with a 1 in 5 dilution of 70 mM oxyhaemoglobin. The absorbance is measured at 580nm. A few drops of a live yeast suspension is added to the cuvette (without significantly changing the volume). The absorbance is remeasured at the same wavelength as above and is found to be 0.40, a decrease of 0.2 on the first measurement. What is the molar absorbance coefficient of the oxyhaemoglobin at 580 nm? (do not enter the units in the answer, 2 decimal places)
