Expressing Concentration Of Solutions

Step 1: Understanding the Concept:
Mass of solution = Volume × Density. Mass of solute = (% by weight/100) × Mass of solution.

Step 2: Detailed Explanation:
Volume = 1 L = 1000 mL. Density = 1.2 g/mL.
Mass of solution = g.
Mass of solute = g.

Step 3: Final Answer:
480 g
