Not really, no.
An aqueous solution is simply a solution that has water as its solvent.
For example, an aqueous solution of potassium nitrate,
In order to prepare this solution, you should first figure out the mass of potassium nitrate that contains
#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
