An aqueous solution of \(98 \%(w / w) \mathrm{H}_2 \mathrm{SO}_4\) has density of \(1.02 \mathrm{~g} / \mathrm{cc}\). The molality of the solution is
- A 1.1
- B 0.7
- C 2.1
- D 1.5
Answer & Solution
Correct Answer
(A) 1.1
Step-by-step Solution
Detailed explanation
\(\because\) Volume \(=\frac{\text { Mass }(m)}{\text { Density }(d)}=\frac{100}{1.02}=98.039 \mathrm{~mL}\) \(\therefore \quad\) Molarity \(=\frac{9.8 \times 1000}{98 \times 98.04}=1.01\) Which is close to 1.1 .
