हिन्दीCalculate the molarity of \( \text{NaOH} \) in a solution prepared by dissolving \( 4\text{ g} \) of it in enough water to form \( 250\text{ mL} \) of solution.
Correct answer · Option 2
0.4 M
Explanation
Moles of NaOH = \( \frac{4}{40} = 0.1\text{ mol} \). Molarity = \( \frac{0.1\text{ mol}}{0.250\text{ L}} = 0.4\text{ mol L}^{-1} \).
