Determine the amount of sodium hypochlorite in Bleach you tolerated a 23.82 ml sample of 0.0100 M KIO cuboid with a solution of

Kisachek [45]

Answer: The moles of KIO cuboid titrated are 0.0002382

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

$Molarity=\frac{n\times 1000}{V_s}$

where,

n = moles of solute

$V_s$ = volume of solution in ml

Now put all the given values in the formula of molarity, we get

$0.0100=\frac{n\times 1000}{23.82}$

$n=0.0002382$

Therefore, the moles of KIO cuboid are 0.0002382
