36. Zinc sulfate and potassium hexacyanoferrate interact according to the equation
3ZnSO4 2K4[Fe(CN)6] = K2Zn3[Fe(CN)6]2 3K2SO4. From a volumetric flask with a capacity of 100 ml, 25 ml of a ZnSO4 solution were taken for titration; in the process of conductometric titration of a sample of 0.09843 n. K4[Fe(CN)6] solution gave the following results:
V, ml 0.0 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 9.0
R, Ohm 0.085 0.094 0.102 0.109 0.117 0.125 0.135 0.147 0.159 0.172
Determine the mass of dissolved zinc sulfate in the flask.
