0.5 मोलर विलयन के 2 लीटर में विलेय के कितने मोल होंगे?
How many moles of solute are present in 2 L of a 0.5 M solution?
Explanation opens after your attempt
Correct Answer
A. 1 मोल / 1 mol
Concept
Molarity = moles/litre, so moles = molarity × volume.
Why this answer is correct
Moles = 0.5 × 2 = 1 mol.
Exam Tip
When molarity and volume are given, multiply to find moles. चरण 1: मोलरता = मोल/लीटर, इसलिए मोल = मोलरता × आयतन। चरण 2: मोल = 0.5 × 2 = 1 मोल। चरण 3: जब मोलरता और आयतन दिए हों, गुणा करके मोल निकालें।
