Calculate the amount of solute dissolved in 160 gram solvent that boils at 85^ C . the molar mass of solute is 120 ~g ~mol ⁻¹ . ( K _ b . for solvent =2.7^ C kg mol ⁻¹ and boiling point of solvent .=76^ C )

Options

  1. A64 gram
  2. B42 gram
  3. C50 gram
  4. D60 gram

Correct answer

A. 64 gram

Step-by-step solution

T _ b =(85-76)=2.7 W _ B 120 1000 160 W _ B =64 ~g
