Correct Answer

A. दोगुनी हो जाएगी / It becomes double

Step 1

Concept

Molarity = moles of solute/volume.

Step 2

Why this answer is correct

If volume is same and moles double, molarity doubles.

Step 3

Exam Tip

When only numerator changes, the ratio changes directly. चरण 1: मोलरता = विलेय के मोल/आयतन। चरण 2: आयतन समान हो और मोल दोगुने हों तो मोलरता दोगुनी होगी। चरण 3: अनुपात में केवल ऊपर की मात्रा बदलने पर प्रभाव सीधा होता है।
