A solution consists of ether and \(5.0 \mathrm{~g}\) of water at \(0^{\circ} \mathrm{C}\). If the ether evaporates completely to freeze the water, then the mass of the ether in the solution is
- A 5 g
- B 4 g
- C 4.5 g
- D 6 g
Answer & Solution
Correct Answer
(B) 4 g
Step-by-step Solution
Detailed explanation
Latent heat of ether \(=90 \mathrm{cal} / \mathrm{g}\) Latent heat of water \(=80 \mathrm{cal} / \mathrm{g}\) Let required mass of ether be ' \(m\) ' So, heat loss by water \(=\) Heat gain by ether…
