Osmotic Pressure Calculation

  1. Apr 26, 2006 #1
    So i have a Chem test tomorrow and out of all the questions on the review this is the only one that i have left. So here it is:

    A 1.0g sample of a molecular compound having a molecular weight of 100,000g/mol is dissolved in 100g of water. Calculate the osmotic pressure of the solution in torr at a temperature of 27deg C. (aaume the volume of the solution is 100mL.)

    I know that the answer is 1.9torr

    Any one up to the challenge?
