Correct Answer

A. 1

Step 1

Concept

Mole fraction shows the part of total moles contributed by a component.

Step 2

Why this answer is correct

All parts together make the whole solution, so their sum is 1.

Step 3

Exam Tip

Mole fraction is not a percentage unless multiplied by 100. चरण 1: मोल अंश कुल मोल में घटक का भाग बताता है। चरण 2: सभी भागों का योग पूरे विलयन के बराबर होता है, इसलिए योग 1 है। चरण 3: मोल अंश कभी प्रतिशत नहीं होता, जब तक उसे 100 से गुणा न करें।
