Question
What is the molarity of pure water at 4°C? (Molar mass of water = 18 g/mol, density = 1 g/mL)
Explanation
55.5M accurately defines or describes the concept asked in this question. Within Water and Mole Concept, precise definitions and terminology are essential for clear scientific communication. The other options (18M, 10M, and 100M) either describe related but distinct concepts, use incorrect terminology, or confuse similar-sounding terms that have different scientific meanings. A thorough understanding of exact definitions helps distinguish between closely related biological concepts and is crucial for competitive examinations.
