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.
where,
n = moles of solute
= volume of solution in ml
Now put all the given values in the formula of molarity, we get
Therefore, the moles of KIO cuboid are 0.0002382
the correct answer is 1.2812 x 10^23. you can get this by multiplying .23 x arogados number / the molar mass of boron (10.81)

Here, we found this answer my looking at the key words 'naturally occurring isotopes'
An isotope is a different amount of neutrons, making the atomic mass change.
