The unit of ebulioscopic constant is …….

Answer»

K kg `MOL^(-1)` or K `("MOLALITY")^(-1)`
mol kg `K^(-1)` or `K^(-1)` (molality)
kg `mol^(-1)K^(-1)` or `K^(-1)("molality")^(-1)`
K mol `kg^(-1)` or K (molality)

SOLUTION :`Delta T_(B)=K_(b).m`
`K_(b)=(Delta T_(b))/(m)=(K)/("Molality")=(K)/(mol kh^(-1))="K kg mol"^(-1)`.
