Answer:

53.6g of water are needed

Explanation:

Solubility is the maximum amount that a solvent can dissolve of a particular solute.

<em>100g of Water can dissolve 140g of KI.</em>

That is also the definition of a satured solution: A solution that is dissolved in the maximum amount in a particular amount of solvent.

If there are dissolved 75.0g of KI, the amount of water needed are:

75g KI * (100g water / 140g KI) =

<h3>53.6g of water are needed</h3>
