Hard Chemistry Chapter 01: Solutions Class 12 Level 5

विलयन बनाते समय यदि अंतिम आयतन सीधे मापा गया है तो मोलरता निकालते समय कौन सा आयतन लेना चाहिए?

If the final volume is measured directly while preparing a solution which volume should be used for calculating molarity?

Explanation opens after your attempt
Correct Answer

C. अंतिम विलयन का मापा गया आयतन / Measured final volume of solution

Step 1

Concept

Molarity means moles of solute per litre of solution.

Step 2

Why this answer is correct

Therefore the final measured volume of the solution must be used.

Step 3

Exam Tip

Do not simply add component volumes when final volume is available. चरण 1: मोलरता की परिभाषा विलेय के मोल प्रति लीटर विलयन है। चरण 2: इसलिए विलायक का अलग आयतन नहीं बल्कि बने हुए विलयन का अंतिम आयतन लेना चाहिए। चरण 3: आयतन जोड़ने में गलती हो सकती है इसलिए मापे गए अंतिम आयतन को प्राथमिकता दें।
