The degree of dissociation of Ca(NO3)2 in a dilute aqueous solution co – InterviewSolution

1.	The degree of dissociation of Ca(NO3)2 in a dilute aqueous solution containing 16.4 g of the salt per 358.2 g of water at 100∘C is 0.7. If the vapour pressure of water at 100 oC is 760 mm Hg, calculate the vapour pressure of the solution in mm Hg
Answer» The degree of dissociation of $C a (N O_{3})_{2}$ in a dilute aqueous solution containing $16.4 g$ of the salt per $358.2 g$ of water at $100^{\circ} C$ is $0.7$ . If the vapour pressure of water at $100^{o} C$ is $760 mm Hg$ , calculate the vapour pressure of the solution in $mm Hg$
