Taking into account the definition of molarity, the molarity of a solution prepared by dissolving 0.2 mol sucrose in enough water to make a 100 mL solution is 2 $\frac{moles}{liter}$ .

<h3>Definition of molarity</h3>

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

$molarity=\frac{number of moles}{volume}$

Molarity is expressed in units $\frac{moles}{liter}$ .

<h3>Molarity in this case</h3>

In this case, you have:

number of moles= 0.2 moles
volume= 100 mL= 0.1 L

Replacing in the definition of molarity:

$molarity=\frac{0.2 mole}{0.1 L}$

Solving:

<u><em>molarity= 2 </em></u> $\frac{moles}{liter}$

Finally, the molarity of a solution prepared by dissolving 0.2 mol sucrose in enough water to make a 100 mL solution is 2 $\frac{moles}{liter}$ .
