Question

words used to tell how strong a solution is based on the amount of solute and solvent.
○ mixture
● homogeneous
○ law of conservation and mass
○ concentration

Explanation:

• A mixture is a combination of substances, not a measure of solution strength.
• Homogeneous describes a uniform mixture, not the strength based on solute/solvent amounts.
• The Law of Conservation of Mass states mass is conserved in reactions, unrelated to solution strength.
• Concentration specifically refers to the amount of solute relative to solvent, which describes how strong a solution is.

Answer:

D. Concentration
