Explanation opens after your attempt
Correct Answer

A. 0.25 मोल / 0.25 mol

Step 1

Concept

Moles = molarity × volume in litres.

Step 2

Why this answer is correct

250 mL = 0.250 L. Moles = 1 × 0.250 = 0.25 mol.

Step 3

Exam Tip

Converting solution volume into litres is the key step. चरण 1: मोल = मोलरता × आयतन लीटर में। चरण 2: २५० मिलीलीटर = ०.२५० लीटर। मोल = १ × ०.२५० = ०.२५ मोल। चरण 3: विलयन का आयतन लीटर में बदलना सबसे जरूरी कदम है।
