Correct Answer

C. ०.३० मोल / 0.30 mol

Step 1

Concept

Moles = molarity × volume in litres.

Step 2

Why this answer is correct

750 mL = 0.750 L. Moles = 0.4 × 0.750 = 0.30 mol.

Step 3

Exam Tip

Writing decimal volume carefully reduces errors. चरण 1: मोल = मोलरता × आयतन लीटर में। चरण 2: ७५० मिलीलीटर = ०.७५० लीटर। मोल = ०.४ × ०.७५० = ०.३० मोल। चरण 3: दशमलव आयतन लिखते समय शून्य लगाना गलती कम करता है।
