If 0.01 ~m aqueous solution of an electrolyte freezes at -0.056 ^ C . Calculate van't Hoff factor for an electrolyte. (Cryoscopic constant of water =1.86 ~K ~kg ~mol ⁻¹ )

Step-by-step solution

T _ f = i K _ f m 0.056= i 1.86 0.01 i = 0.056 1.86 0.01 =3.01 [Note: In the question, the freezing point of aqueous solution is changed from -0.056 ~K to -0.056^ C to apply appropriate textual concepts.]
