(AIEEE 2004) molecules of urea are present in of its solution. The concentration of urea solution is — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{Moles} = (6.02 \times 10^{20}) / (6.02 \times 10^{23}) = 10^{-3}\text{ mol}$. <br>$\text{Molarity} = 10^{-3}\text{ mol} / 0.1\text{ L} = 0.01\text{ M}$. [1, 2]
