Homework Help: Vapor Pressure Lowering

  1. Oct 16, 2005 #1
    I calculated that there is 41/90 mol glucose and 92/3 mol water. Then I calculated the molar fraction of solvent in the solution, which I found to be .985. Next I multiplied the .985 by 23.76 mmHg and came up with 23.4 mmHg. To find the "lowering," I subtracted this from 23.76 coming up with a final answer of .348 mmHg.

    Assuming I didn't make any arithmetic errors, is my process correct?

    Thank you.

    Yes. There is a math error in the calculation of the mole fraction.
