If the elevation in boiling point of a solution of 10 gm of solute (mol wt.=100) in 100 gm of water is DeltaT _(b), the ebullioscopic constant of water is

Answer»

10
`10Delta T _(b)`
`Delta T_(b)`
`(DeltaT_(b))/(10)`

SOLUTION :`Delta T_(b) (K_(b)xxw xx1000)/(M xxW)`
`therefore K _(b) =(K_(b) XX 100xx100)/( 10xx1000) = Delta T_(b)`
