Which of the following pairs of solutions is isotonic? — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

Molarity of 6% Urea is given by: 0.6 10 M = 0.1 60 urea M x Osmotic pressure of 6% urea will be: 0.1 urea R T x x Molarity of 18% Fructose is given by: 1.8 10 0.1 180 fructose M M x Osmotic pressure of 6% urea will be: 0.1 fructose R T x x Since the osmotic pressure is the same, 6% of urea will be isotonic with 18% fructose.
