Question

the vant hoff factor for 0.3 molal aqueous solution of urea is ​

Answer 1

Answer:

● Answer-

i = 1

● Explaination-

- Van't hoff factor is defined as ratio of no of molecules after dissociation (association) to no of molecules before dissociation (association).

i = N(after) / N(before)

- As urea is a non-electrolyte it doesn't dissociative into aqueous solution.

- As N(after) = N(before), value of i = 1.
