The molarity of a \(\mathrm{NaOH}\) solution by dissolving \(4 \mathrm{~g}\) of it in \(250 \mathrm{ml}\) water is
- A \(0.4 \mathrm{M}\)
- B \(0.8 \mathrm{M}\)
- C \(0.2 \mathrm{M}\)
- D \(0.1 \mathrm{M}\)
Answer & Solution
Correct Answer
(A) \(0.4 \mathrm{M}\)
Step-by-step Solution
Detailed explanation
Hints : Molarity \(=\frac{4 / 40}{250 / 1000}=0.4\)
