It makes little difference which we call the solute and which the solvent. USUALLY we call the smaller amount the solute and the larger amount the solvent. The question is a not a very good one.
False. Air is actually a mixture of gases, not a solution. It consists of mainly nitrogen (about 78%) and oxygen (about 21%), with trace amounts of other gases such as argon, carbon dioxide, and various pollutants. In a solution, such as saltwater, there is a solute dissolved in a solvent. In the case of air, there is no solute dissolved in a solvent, so it cannot be considered a solution.
