250 मिलीलीटर 2 मोलर विलयन में विलेय के कितने मोल होंगे?

How many moles of solute are present in 250 mL of 2 molar solution?

Explanation opens after your attempt
Correct Answer

A. 0.5 मोल0.5 mole

Step 1

Concept

Volume 250 mL = 0.25 L.

Step 2

Why this answer is correct

Moles = molarity × volume = 2 × 0.25 = 0.5 mole.

Step 3

Exam Tip

Use volume in litres while finding moles from molarity. चरण 1: आयतन 250 मिलीलीटर = 0.25 लीटर। चरण 2: मोल = मोलरता × आयतन = 2 × 0.25 = 0.5 मोल। चरण 3: मोलरता से मोल निकालते समय आयतन लीटर में लें।
