Question

A 0.561 m solution of unknown electrolytic depresses the freezing point of water by 2.93 C. What is Bob't Hoff factor for this electrolyte. The freezing point depression f oh r water is 1.86 C kg/mol

Answer 1

Answer:

Explanation:

firstly its van't hoff factor(i)

ΔT=iK(f)m

i=ΔT/K(f)m

i=2.93/(1.86*0.561)

i=2.8
