Using the equations and values given below, calculate:

- Concentration of standard Na2S2O3 solution: 0.01057M

-Tempurature of equilibrium mixture: 20.4C

- Total Concentration of Reducible Iodine [I2+I3-] in aqueous phase: 0.017168917M

Concentration of Iodine in CH2Cl2: 0.017801937M

Eq1. I2(aq)+I^- I3^-(aq)

Eq2. Kc= [I3^-(aq)]/[I2(aq)][I^-(aq)]

Eq3. I2(aq) I2(CH2Cl2)

Eq4. K= [I2(CH2Cl2)]/[I2(aq)] = 176 @ (suppose 25, but ok to use) 20.4C

Eq5. I2(aq) + 2S2O3^2-(aq) --> 2I^-(aq) + S4O6^2-(aq)

Eq6. I3^-(aq) + 2S2O3^2-(aq) --> 3I^-(aq) + S4O6^2-(aq)

Eq7. [I^-(aq)] = 0.200molL^-1 -[I3^-(aq)]
