Question

The unit of ebullioscopic constant is

पर्याय

• K kg mol^–1 or K^–1 (molarity)^–1

• mol Kg K^–1 or K^–1 (molarity)

• kg mol^–1 k or K^–1 (molarity)^–1

• K mol kg^–1 or K (molarity)

Answer 1

K kg mol^–1 or K^–1 (molarity)^–1 

Explanation:

As we know from elevation in boiling point that U

ΔT_b = K_bm

Unit of K_b = `("Unit of"  ΔT_b)/"Unit of m"`

= `K/(mol  kg^-1)`

= K mol^–1 kg
