Expert Chemistry Chapter 01: Solutions Class 12 Level 4

शून्य दशमलव चार मोलर विलयन के एक सौ पचास मिलीलीटर को जल मिलाकर छः सौ मिलीलीटर किया गया। नई मोलरता क्या होगी?

150 mL of 0.4 M solution is diluted with water to 600 mL. What is the new molarity?

Explanation opens after your attempt
Correct Answer

A. 0.10 मोलर / 0.10 M

Step 1

Concept

Amount of solute does not change during dilution.

Step 2

Why this answer is correct

New molarity = 0.4 × 150/600 = 0.10 M.

Step 3

Exam Tip

Volume becomes four times, so molarity becomes one-fourth. चरण 1: विलेय की मात्रा पतला करने पर नहीं बदलती। चरण 2: नई मोलरता = 0.4 × 150/600 = 0.10 मोलर। चरण 3: आयतन चार गुना हो गया, इसलिए मोलरता एक चौथाई हो जाएगी।
