Correct Answer

C. 0.50 मोल प्रति लीटर / 0.50 mol L-1

Step 1

Concept

Molarity = moles ÷ volume in litres.

Step 2

Why this answer is correct

600 mL = 0.6 L. Molarity = 0.30 ÷ 0.6 = 0.50 mol L^-1.

Step 3

Exam Tip

When volume is less than one litre, molarity can be greater than the number of moles. चरण 1: मोलरता = मोल ÷ आयतन लीटर में। चरण 2: ६०० मिलीलीटर = ०.६ लीटर। मोलरता = ०.३० ÷ ०.६ = ०.५० मोल प्रति लीटर। चरण 3: आयतन लीटर में छोटा होने पर मोलरता मोल से बड़ी हो सकती है।
