Which of the following pairs of solution is isotonic? (molar mass. urea =60 , sucrose =342 ~g ~mol ⁻¹ )

Options

  1. A3 0 ~g ~L ⁻¹ urea and 17 19 gL ⁻¹ sucrose
  2. B0 3 gL ⁻¹ urea and 1 719 gL ⁻¹ sucrose
  3. C3 0 gL ⁻¹ urea and 1 719 gL ⁻¹ sucrose
  4. D0 3 ~g ~L ⁻¹ urea and 17 19 gL ⁻¹ sucrose

Correct answer

A. 3 0 ~g ~L ⁻¹ urea and 17 19 gL ⁻¹ sucrose

Step-by-step solution

For isotonic solution, _ ures = _ sucrose array l n _ urea = n _ oucinose 3.0 6.0 = 17.19 343 =0.05 ~mol array
