Here's why:

* Solution: A homogeneous mixture of two or more substances.

* Solute: The substance that dissolves in the solvent.

* Solvent: The substance that dissolves the solute.

Think of a glass of iced tea:

* Solvent: Water

* Solutes: Sugar, tea leaves (which contain various compounds)

Therefore, the iced tea has two or more solutes (sugar and various tea compounds) dissolved in the water (solvent).

Examples of multiple solutes:

* Seawater: Contains salt (sodium chloride), magnesium, calcium, and other minerals.

* Fruit punch: Contains sugar, fruit juices, and flavorings.

* Air: Contains nitrogen, oxygen, carbon dioxide, and other gases.

So, a solution can have one or more solutes, depending on the substances being mixed.
