  1. One has to know pressure and temperature to find volumes of gas given moles or mass. I am getting somewhat annoyed that this is being reposted.

  2. The only way to report the yield with the data given is in 'general' terms of number of molar Volumes (nVm). BP is correct, you will need Temp and Pressure values to calculate specific volumes.

    N2 + 3H2 => 2NH3
    85gms N2 = 3.04mole N2 => 2(3.04mole NH3) = 6.08Vm NH3. Vm is Temperature-Pressure dependent, but given (P,V) ... from the Ideal Gas Law Vm = (nRT/P)/(moles NH3) => Specific molar Volume.
