\(18 \mathrm{~g}\) of glucose is dissolved in \(90 \mathrm{~g}\) of water. The relative lowering of vapour pressure of the solution is equal to
- A \(6\)
- B \(0.2\)
- C \(5.1\)
- D \(0.02\)
Answer & Solution
Correct Answer
(D) \(0.02\)
Step-by-step Solution
Detailed explanation
From Rault’s law for non-volatile solute, we know that \(\frac{p^{\circ}-p_s}{p^{\circ}}=\frac{n_2}{n_1+n_2}\) For dilute solution, relative lowering of vapour pressure,…
