The correct reaction between elevation of boiling point and molar of solute is

Answer»

`M_(2) = (K_(b).W_(2))/(DeltaT_(b).W_(1))`
`M_(2) = (K_(b). W_(1))/(DeltaT_(b). W_(2))`
`M_(2) = (DeltaT_(b). K_(b))/(W_(1).W_(2))`
`M_(2) = (DeltaT_(b). W_(1))/(K_(b). W_(2))`

SOLUTION :`DeltaT_(b) = (K_(b) xx W_(2))/(W_(1) xx M_(2))`
HENCE, `M_(2) = (K_(b) xx W_(2))/(DeltaT_(b) xx W_(1))`
