We know that one mole of N2 at S.T.P. occpies 22.4 litres and  contains 6.022 x 1023 molecules of N2.
Therefore, 22.4 litres of N2 at S.T.P. contains molecules = 6.022 x 1023
                 1 litres of N2 at S.T.P. contains molecules = (6.022 x 1023)/22.4
                 32 litres of N2 at S.T.P. contains molecules = (32 x 6.022 x 1023)/22.4
                                                                              = 8.603 x1023
