Correct Answer

A. दोगुनी हो जाएगी / It becomes double

Step 1

Concept

Molarity is found by dividing moles by volume.

Step 2

Why this answer is correct

If volume is halved with same moles, molarity doubles.

Step 3

Exam Tip

A concentrated solution has the same solute in a smaller volume. चरण 1: मोलरता मोल को आयतन से भाग देकर मिलती है। चरण 2: आयतन आधा होने पर वही मोल कम आयतन में होंगे, इसलिए मोलरता दोगुनी होगी। चरण 3: सांद्र विलयन में कम आयतन में अधिक प्रभाव होता है।
