The relative lowering of vapour pressure of a sugar solution in water is3.5xx 10^(-3)The mole fraction of water in that solution is

Answer»

<P>`0.0035`
`0.35`
`0.0035//18`
`0.9965`

Solution :`(Delta P )/(P ^(@))= X _("SUGAR")`
`3.5 xx 10 ^(-3) =x _("sugar")`
`x _("sugar") + x _(H _(2)O)=1`
`x _(H_(2)O)=1 -0.0035 = 0.9965`
