A 5.2 molal aqueous solution of methyl alcohol, CH ₃ OH , is supplied. What is the mole fraction of methyl alcohol in the solution?

Options

  1. A0.190
  2. B0.086
  3. C0.050
  4. D0.100

Correct answer

B. 0.086

Step-by-step solution

aligned Molefraction of solute ( X ₂ ) in aqueous solution & = m m + 1000 18 & = 5.2 5.2+ 1000 18 =0.09 aligned
