Some Basic Concepts (Mole Concept) · Class 11 · JEE Main Previous Year Question
A solution is prepared by adding of to mole of water. Mass percent of in solution is:
- a
- b
- c
- d✓
🧠 Mass percent uses the total solution mass of water is . Add the of solute and you get of solution.
🗺️ One quick step
⚠️ The "divide by water" trap If you divide by (water alone), you get — close to but wrong in concept. Always divide by total solution mass.
