What is the molarity of pure water? (Density ) — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
What is the molarity of pure water? (Density $= 1\text{ g/mL}$)
Answer: 55.5
💡 Solution & Explanation
$\text{Mass of 1 L} = 1000\text{ g}$. <br>$\text{Moles in 1 L} = 1000 / 18 = 55.55\text{ mol}$. <br>Thus, molarity is $55.55\text{ M}$.
