Explanation:
As molarity is the number of moles placed in a liter of solution. Therefore, no. of mole = Molarity × volume of solution in liter
Hence, moles of will be calculated as follows.
No. of mole of =
= 0.0168 mole
According to the given reaction, 2 mole of react with 4 mole of KI.
Therefore, for 0.0168 mole amount of required will be as follows.
=
= 0.0337 mole of KI
Hence, volume of KI required will be calculated as follows.
Volume =
Volume of KI =
= 0.1614 liter
= 161.4 ml (as 1 L = 1000 mL)
Thus, we can conclude that 161.4 ml volume of a 0.2089 M KI is required for the given situation.
