Correct Answer

A. 20 प्रतिशत / 20 percent

Step 1

Concept

Total moles = 2 + 8 = 10.

Step 2

Why this answer is correct

Mole fraction of solute = 2 ÷ 10 = 0.2, so mole percent = 20 percent.

Step 3

Exam Tip

Multiply mole fraction by 100 to convert it into mole percent. चरण 1: कुल मोल = दो + आठ = दस। चरण 2: विलेय का मोल अंश = दो ÷ दस = शून्य दशमलव दो, इसलिए मोल प्रतिशत = बीस प्रतिशत। चरण 3: मोल अंश को प्रतिशत में बदलने के लिए सौ से गुणा करें।
