The P.P. of ethane over a saturated solution containing 6.56 xx 10^(-2) g of ethane is 1 bar. If the solution contains 5 xx 10^(-2) g of ethanol, then what shall be its P.P? (P.P = Partial pressure).

Answer»


SOLUTION :`S propto P`
`S_(1)/S_(2) =P_(1)/P_(2)`
`P_(2) =("1 bar" xx 5 xx 10^(-2))/(5.56 xx 10^(-2)) = 0.762`
