Question #6ddc0

Answer 1

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, `"KNO"_3`, will have this salt as the solute and water as the solvent.

A `"1.25-M"` solution of potassium nitrate must contain `1.25` moles of potassium nitarte for every `"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 `"126.4 g"` of potassium nitrate in about `"500 mL"` of water, then add enough water until the total volume of the solution reaches `"1 L"`.
