Correct Answer

B. दोगुनी होगी / It will be double

Step 1

Concept

Molarity = moles ÷ volume.

Step 2

Why this answer is correct

If moles are same and volume is half, the ratio becomes double.

Step 3

Exam Tip

Molarity is inversely related to volume. चरण 1: मोलरता = मोल ÷ आयतन। चरण 2: मोल समान हों और आयतन आधा हो, तो अनुपात दोगुना हो जाता है। चरण 3: मोलरता आयतन से उलटा संबंध रखती है।
