Correct Answer

A. 12:88

Step 1

Concept

12 percent means 12 g solute in 100 g solution.

Step 2

Why this answer is correct

Mass of solvent = 100 - 12 = 88 g, so the ratio is 12:88.

Step 3

Exam Tip

In mass percent, distinguish solution from solvent. चरण 1: 12 प्रतिशत का अर्थ 100 ग्राम विलयन में 12 ग्राम विलेय है। चरण 2: विलायक का द्रव्यमान = 100 - 12 = 88 ग्राम, इसलिए अनुपात 12:88 है। चरण 3: द्रव्यमान प्रतिशत में विलयन और विलायक को अलग-अलग पहचानें।
