pressure questions?

(1)A 1.00 litre tank is filled with 1.00 g each of F2, O2 and N2 gas.

 Calculate the mole fraction of F2.

(2)A 1.00 litre tank is filled with 1.00 g each of F2, O2 and N2 gas.

What is the partial pressure of N2 if the pressure in the container is 1.00 atm?

    a.   convert each to moles using the molar mass.

       ...  /ex --  1.00g O2 X  1mole/32.0g  =  0.03125 mol O2

     ... you do the rest

      ...  now add all -- to get total moles

      finally  ==  mol F2 / total mol  =  mole fraction of F2

    b.  proportion

         mol N2 / total mole = P(N2) / 1atm  ...  solve for P(N2)
