Correct Answer

A. 0.1 मोल0.1 mol

Step 1

Concept

500 mL = 0.5 L.

Step 2

Why this answer is correct

Moles = 0.2 × 0.5 = 0.1 mol.

Step 3

Exam Tip

In half a litre, a 0.2 M solution contains half of 0.2 mole. चरण 1: 500 मिलीलीटर = 0.5 लीटर। चरण 2: मोल = 0.2 × 0.5 = 0.1 मोल। चरण 3: आधा लीटर में 0.2 मोलर का आधा मोल मान आएगा।
