The molality of solution, when \(18 \mathrm{~g}\) of glucose is added to the \(18 \mathrm{~g}_{\text {of } \mathrm{H}_2 \mathrm{O} \text { is }}\)
- A \(0.55 \mathrm{~m}\)
- B \(2.55 \mathrm{~m}\)
- C \(5.55 \mathrm{~m}\)
- D \(55.5 \mathrm{~m}\)
Answer & Solution
Correct Answer
(C) \(5.55 \mathrm{~m}\)
Step-by-step Solution
Detailed explanation
\begin{aligned} & \text {} \mathrm{m}_2=18 \mathrm{~g}, \mathrm{M}_2=180 \mathrm{~g} \mathrm{~mol}^{-1}, \mathrm{~m}_1=18 \mathrm{~g}, \mathrm{M}_1=18 \mathrm{~g} \\ & \begin{aligned} \Rightarrow \mathrm{n}_2=\frac{\mathrm{m}_2}{\mathrm{M}_2} & =\frac{18}{180}=0.1 \mathrm{~mol}…
