Yasmin's teacher tells her that the solubility of salt is 360 g/L at room temperature (25 °C). How can Yasmin make an unsaturated salt solution?

By adding less amount or quantity of the salt (solute), than the medium (solvent) can dissolve at a particular temperature that is to make an unsaturated solution at room temperature, Yasmin should add less than 360 g of salt to one liter of the solvent

Explanation:

An unsaturated solution is one that consists of less than the maximum mass or quantity of the solute that it is capable of dissolving.
