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

[chemconfusion]

Homework Statement

Calculate the volume of H₂ required to completely hydrogenate 50 grams of glycerol trioleate at 1 atm pressure and 25 degrees celsius. The ideal gas constant is 0.082.

Homework 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.

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.
