✔ 最佳答案
A. A solution containing 20.0 g of NaCl and 100.0 g of water.
Solvent = water
Solute = NaCl
[When a solid (NaCl) and a liquid (water) form a solution, the liquid is the solvent and the solid is the solute.]


B. A solution containing 50.0 mL of propanol and 30.0 mL of water.
Solvent = propanol
Solute = water
[When two liquids form a solution, the liquid with a larger volume (propanol) is the solvent and that with a smaller volume (water) is the solute.]


C. A solution containing 0.5 g of AgNO₃ and 15 mL of water.
Solvent = water
Solute = AgNO₃
[When a solid (AgNO₃) and a liquid (water) form a solution, the liquid is the solvent and the solid is the solute.]
