Answer & Solution

Correct Answer

(A) \(752.4\)

Step-by-step Solution

Detailed explanation

According to Raoult's Law \(\frac{P^{\circ}-P_{s}}{P_{s}}=\frac{W_{B} \times M_{A}}{M_{B} \times W_{A}} \quad \ldots(i)\) Here \(P^{\circ}=\) Vapour pressure of pure solvent, \(P_{s}=\) Vapour pressure of solution \(W_{B}=\) Mass of solute, \(W_{A}=\) Mass of solvent \(M_{B}=\)…
