Homework Help: Calculating the vol. of hydrogen needed to hydrogenate under certain conditions

  1. Oct 25, 2008 #1
    1. The problem statement, all variables and given/known data Calculate the volume of H2 required to completely hydrogenate 50 grams of glycerol trioleate at 1 atm pressure and 25 degrees Celcius. The ideal gas constant is 0.082.

    2. Relevant equations I am unsure if I need the Ideal Gas Equation or not. I know that the ideal gas constant is 0.082 and that there are .057 moles of glycerol trioleate that need to be hydrogenized.

    3. The attempt at a solution I am at a loss at where to start. I am not necessarily looking for an answer, but guidance as to how to go about this.

    Start with the reaction equation, this is simple stoichiometry.
