Answer #1

initial concentration of KIO₃ = 0.00364 M

Explanation

Total volume = 20.0 mL + 10.0 mL + 80.0 mL = 110.0 ml

According to dilution law, C1 * V1 = C2 * V2

C1 = concentration before mixing = 0.0200 M

V1 = volume before mixing = 20.0 mL

C2 = concentration after mixing

V2 = volume after mixing = 110.0 mL

C2 = C1 * (V1 / V2)

C2 = 0.0200 M * (20.0 mL / 110.0 mL)

C2 = 0.0200 M * (0.182)

C2 = 0.00364 M
