\(\mathrm{H}_2 \mathrm{SO}_4\) નું એક દ્રાવણ જે દળ વડે \(31.4 \% \mathrm{H}_2 \mathrm{SO}_4\) અને \(1.25 \mathrm{~g} / \mathrm{mL}\) ઘનતા ધરાવે છે. તો \(\mathrm{H}_2 \mathrm{SO}_4\) દ્રાવણની મોલારિટી _______ \(\mathrm{M}\) છે.(નજીકનો પૂણાંક) [આપેલ \(\mathrm{H}_2 \mathrm{SO}_4\) નું મોલર દળ = \(98 \mathrm{~g} \mathrm{~mol}^{-1}\) છે.]

  1. A \(4\)
  2. B \(3\)
  3. C \(2\)
  4. D \(1\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(4\)

Step-by-step Solution

Detailed explanation

\( \mathrm{M}=\frac{\mathrm{n}_{\text {solute }}}{\mathrm{V}} \times 1000 \) \( =\frac{\left(\frac{31.4}{98}\right)}{\left(\frac{100}{1.25}\right)} \times 1000 \) \( =4.005 \approx 4\)
