You will want to use the Ideal gas law equation PV = nRT where T is temperature in degrees Kelvin. The R is the gas constant. You already have the number of moles and volume so just plug in values with proper units to calculate pressure.
R value = 0.082057338(47) L atm K−1 mol−1
The SI unit for pressure is pascals, but some times the problem will call for pressure measured in atmospheres.

Temperature must be converted to degrees Kelvin from degrees Celsius. Add 273.15 to 20 to get temp in K. The only other potential problem would be the value you are using for R.

I am using the right value for R, right?

R = 0.0821 L*atm/k*mol, not 8.31. That's for kPa units of pressure.
