The degree of dissociation of Ca(NO(3))(...

The degree of dissociation of `Ca(NO_(3))_(2)` in a dilute aqueous solution containing `7 g` of salt per `100 g` of water at `100^(@)C` is `70%`. Calculate the vapour pressure of solution.

Text Solution

Verified by Experts

The correct Answer is:
`746.10mm`
`P_(s)P^(@) xx X_("solvent")`
`= 760 xx (((100-7)/(18)))/([5.167 +(7)/(164)(1+2xx0.7)])`
`=760 xx (5.167)/(5.167 +0.102)`
`= 760 xx (5.167)/(5.269) = 760 xx 0.98 = 745.3 mm`
