Question

A 0.6 solution of urea would be isotonic with

Answer 1

here molarity of given data i.e.0.6% solution urea=0.1 M

by d formula M=10x/Mol Wt. (x=given %)

i.e. 0.6*10/60

now verifiy wid d given options.... 0.1 M gulcose is isotonic.

KCl is ionic so it dissociates and 0.6% glucose=0.03 M

i hope its correct...:)
