An aqueous solution containing 0.10 g `KIO_(3)` (formula weight`=214.0`) was treated with an excess of KI solution the solution was acidified with HCl. The liberated `I_(2)` consumed 45.0 " mL of " thiosulphate solution to decolourise the blue starch-iodine complex. Calculate the molarity of the sodium thosulphate solution.

Explanation

To calculate the molarity of the sodium thiosulphate solution, we will follow these steps:

### Step 1: Calculate the moles of KIO₃
We start by calculating the number of moles of KIO₃ using the formula:
\[ \text{Moles of KIO}_3 = \frac{\text{mass of KIO}_3}{\text{molar mass of KIO}_3} \]
Given:
...
