Question

0.1M urea solution us isotonic with.... Solution

Answer 1

Explanation:

0.1 M urea solution is isotonic with 0.05 M NaCl solution. Both solutions will give the same number of particles per unit volume of solution. Urea is non-electrolyte and doesn't dissociate in solution. NaCl is a strong electrolyte. One NaCl molecule dissociates to give two ions. Thus for both solutions the product, i×m is the same which is 0.1
