Molar mass of N2 is 28(since atomic weight of nitrogen is 14and forN2=14*2). So mass of 1 mole of N2 is 28g.Therefore mass of 0.5 mole is 28/2 =14g
Comments

N2 mass =28 for 1 mole For .5 mole (28/2)=14

Atomic Number of N2 gas is 14 and therefore the molecular weight is 14 x 2 = 28 gm Therefore the mass of 0.5 mole of N2 is 28/2 = 14 gm Ans

Mass of N2= 14*2 = 28g Mass of 0.5 mole = 28/0.5 =14g

N2 has two atoms and atomic number OF Nitrogen is 7. so it`s molecular mass = 14 amu (7 protons and 7 neutrons) molecular mass of one mole of N2 = 28 gm/mole so mass of .5 mole of N2 = .5x28 gm = 14 gm.
