\(6.84 \mathrm{~g}\) of sucrose is dissolved in \(200 \mathrm{~g}\) of water. The molality of the solution is
- A \(0.2 \mathrm{M}\)
- B \(0.3 \mathrm{M}\)
- C \(0.1 \mathrm{M}\)
- D \(0.02 \mathrm{M}\)
Answer & Solution
Correct Answer
(C) \(0.1 \mathrm{M}\)
Step-by-step Solution
Detailed explanation
Molar mass of sucrose \(\left(\mathrm{C}_{12} \mathrm{H}_{22} \mathrm{O}_{11}\right)=342\) Molality \(=\frac{\frac{\text { Meight of sucrose }}{\text { Molar mass of sucrose }}}{\text { Mass of solvent }(g)} \times 1000\)…
