Not really, no.

#### Explanation:

An aqueous solution is simply a solution that has water as its solvent.

For example, an aqueous solution of potassium nitrate, ${\text{KNO}}_{3}$, will have this salt as the solute and water as the solvent.

A $\text{1.25-M}$ solution of potassium nitrate must contain $1.25$ moles of potassium nitarte for every $\text{1 L}$ of solution.

In order to prepare this solution, you should first figure out the mass of potassium nitrate that contains $1.25$ moles of this salt. To do that, sue the compound's molar mass

1.25 color(red)(cancel(color(black)("moles KNO"_3))) * "101.1 g"/(1color(red)(cancel(color(black)("mole KNO"_3)))) = "126.4 g"#

So, to make your solution, dissolve $\text{126.4 g}$ of potassium nitrate in about $\text{500 mL}$ of water, then add enough water until the total volume of the solution reaches $\text{1 L}$.
