हिन्दीWhat volume of \( 1.0\text{ M} \) \( \text{NaOH} \) solution is required to prepare \( 1\text{ L} \) of \( 0.2\text{ M} \) \( \text{NaOH} \) solution?
Correct answer · Option 4
200 mL
Explanation
Using molarity equation: \( M_1 V_1 = M_2 V_2 \Rightarrow 1.0 \times V_1 = 0.2 \times 1000 \Rightarrow V_1 = 200\text{ mL} \).
