Explanation opens after your attempt
Correct Answer
A. 0.2 मोल / 0.2 mol
Concept
Moles = molarity × volume in litres.
Why this answer is correct
0.1 × 2 = 0.2 mol.
Exam Tip
To find moles from molarity, multiply, not divide. चरण 1: मोल = मोलरता × लीटर में आयतन। चरण 2: 0.1 × 2 = 0.2 मोल। चरण 3: मोलरता से मोल निकालते समय भाग नहीं, गुणा करें।
