A solution of glucose (C6H12O6) is isotonic with 4 g of urea (NH2 - CO - NH2 ) per liter of solution. The concentration of glucose is :
Correct answer: C. 12 g/l
- A. 4 g/l
- B. 8 g/l
- C. 12 g/l
- D. 14 g/l
Explanation
Isotonic solutions are those solutions, which have the same osmotic pressure, this means that they have the same concentrations.

About Solutions and Colloids
Solutions are described using molarity, molality, normality, mole fraction, percentage concentration and parts per million. Coverage also includes vapour-pressure lowering, boiling-point elevation, freezing-point depression and osmotic pressure, then distinguishes true solutions, colloids and suspensions by particle size, stability, light scattering and settling.
