Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Definitions and units of concentration terms.
Step 2: Matching
PPM (Parts Per Million): Used for very dilute solutions. (A-IV) Molarity: Defined as moles of solute per liter of solution. Unit: mol $L^{-1}$. (B-I) Molality: Moles per kg of solvent. It involves mass, so it is independent of temperature. (C-III) Mole fraction: Ratio of moles of one component to total moles. It has no units. (D-II)
Step 3: Conclusion
The correct match is A-IV, B-I, C-III, D-II.
Final Answer:(A)
