हिन्दीCalculate the molarity of a solution prepared by dissolving \( 4\text{ g} \) of \( \text{NaOH} \) in enough water to form \( 250\text{ mL} \) of solution.
Correct answer · Option 4
0.4 M
Explanation
Molarity \( M = \frac{\text{Moles of solute}}{\text{Volume in L}} = \frac{4/40}{0.250} = \frac{0.1}{0.250} = 0.4\text{ M} \).
