Solutions MCQ questions with answers
The first 3 of 20 questions. Unlock the series for the rest, each with a solution.
Q1. Match List I (quantity) with List II (SI/commonly used unit). List I: A. Molality; B. Molarity; C. Osmotic pressure; D. Cryoscopic constant (Kf). List II: 1. mol L⁻¹; 2. K kg mol⁻¹; 3. mol kg⁻¹; 4. atm. Select the correct matching:
सूची I (राशि) का सूची II (SI/सामान्यतः प्रयुक्त मात्रक) के साथ मिलान कीजिए। सूची I: A. मोललता; B. मोलरता; C. परासरण दाब; D. हिमांक अवनमन स्थिरांक (Kf)। सूची II: 1. mol L⁻¹; 2. K kg mol⁻¹; 3. mol kg⁻¹; 4. atm। सही मिलान का चयन कीजिए:
- A. A-3, B-1, C-2, D-4
- B. A-3, B-1, C-4, D-2
- C. A-2, B-1, C-4, D-3
- D. A-1, B-3, C-4, D-2
Solution
Molality is moles of solute per kilogram of solvent (mol kg⁻¹), molarity is moles per litre of solution (mol L⁻¹), osmotic pressure is a pressure expressed in atm, and the cryoscopic constant Kf has units of K kg mol⁻¹, giving A-3, B-1, C-4, D-2.
मोललता विलायक के प्रति किलोग्राम में विलेय के मोल (mol kg⁻¹) है, मोलरता विलयन के प्रति लीटर में मोल (mol L⁻¹) है, परासरण दाब atm में व्यक्त एक दाब है, और हिमांक अवनमन स्थिरांक Kf का मात्रक K kg mol⁻¹ है, जिससे A-3, B-1, C-4, D-2 प्राप्त होता है।
Q2. A solution contains 1 mole of a non-volatile, non-electrolyte solute dissolved in 9 moles of a solvent. The relative lowering of vapour pressure of the solution is:
एक विलयन में 9 मोल विलायक में घुले हुए एक अवाष्पशील, अवैद्युत-अपघट्य विलेय का 1 मोल है। विलयन के वाष्प दाब में आपेक्षिक अवनमन है:
- A. 0.11
- B. 0.9
- C. 0.1
- D. 1.0
Solution
Relative lowering of vapour pressure equals the mole fraction of solute = 1/(1+9) = 0.1.
वाष्प दाब में आपेक्षिक अवनमन विलेय के मोल प्रभाज के बराबर होता है = 1/(1+9) = 0.1।
Q3. An ideal semipermeable membrane used in the study of osmosis allows the passage of:
परासरण के अध्ययन में प्रयुक्त एक आदर्श अर्धपारगम्य झिल्ली किसके मार्ग की अनुमति देती है:
- A. both solvent molecules and solute particles freely / विलायक अणु और विलेय कण दोनों मुक्त रूप से
- B. solute particles but not solvent molecules / विलेय कण परंतु विलायक अणु नहीं
- C. neither solvent molecules nor solute particles / न विलायक अणु न ही विलेय कण
- D. solvent molecules but not solute particles / विलायक अणु परंतु विलेय कण नहीं
Solution
A semipermeable membrane permits the smaller solvent molecules to pass through while blocking the larger solute particles; this selective passage is what drives osmosis.
अर्धपारगम्य झिल्ली छोटे विलायक अणुओं को आर-पार जाने देती है जबकि बड़े विलेय कणों को रोकती है; यही चयनात्मक मार्ग परासरण को चलाता है।
