A 60 ml sample solution of KI was electrolysed for 579 sec using a 5 amp constant current. The   produced, completely reacted with 0.20 M sodium thiosulphate solution and unreacted KI solution required 30 ml of 0.04 M acidic solution of KMnO4. If the original molarity of KI solution can be expressed in scientific notation as Y × 10-1. Calculate the value of Y.
