<u>Answer:</u> The amount of sodium thiosulfate required is $2.62\times 10^{-5}$ moles

<u>Explanation:</u>

Moles of $KIO_3$ solution given = 0.0000524 moles

The chemical equation for the reaction of potassium iodate and sodium thiosulfate follows:

$2KIO_3+Na_2S_2O_3\rightarrow K_2S_2O_3+2NaIO_3$

By Stoichiometry of the reaction:

2 moles of potassium iodate reacts with 1 mole of sodium thiosulfate

So, 0.0000524 moles of potassium iodate will react with = $\frac{1}{2}\times 0.0000524=0.0000262mol$ of sodium thiosulfate

Hence, the amount of sodium thiosulfate required is $2.62\times 10^{-5}$ moles
