0.2 मोलर विलयन के 500 मिलीलीटर में विलेय के मोल कितने होंगे?
How many moles of solute are present in 500 mL of a 0.2 M solution?
Explanation opens after your attempt
Correct Answer
A. 0.1 मोल / 0.1 mol
Concept
500 mL = 0.5 L.
Why this answer is correct
Moles = 0.2 × 0.5 = 0.1 mol.
Exam Tip
In half a litre, a 0.2 M solution contains half of 0.2 mole. चरण 1: 500 मिलीलीटर = 0.5 लीटर। चरण 2: मोल = 0.2 × 0.5 = 0.1 मोल। चरण 3: आधा लीटर में 0.2 मोलर का आधा मोल मान आएगा।
