Calculate osmotic Pressure?

I attempted to answer this question twice and i am on my last try, I missed them because I do not know how to use the van't hoff factor in this problem.

Question:

Calculate the Osmotic Pressure of a .0495 M FeCl3 solution at 25 degrees C (The van't hoff factor for FeCl3 is 3.04)

Update:

Thank you Charlie

    Osmotic pressure= iMRT where i is the van't hoff factor.

    R=.0821

    OP=(3.04)(.0495)(298K)(.0821)

    =3.68 atm
