The percentage of urea in an aqueous solution which is isotonic with a 34.2% solution of sucrose is
An aqueous solution of sucrose (C12H22O11) containing 34.2 g/L of sucrose has an osmotic pressure of 2.38 atm at 17° C. For an aqueous solution of glucose (C6H12O6) to be isotonic with this solution, it's concentration (in g/L) should be:
