Question

calculate liue mass of 0.5 mole of N2 gas​

Answer 1

Answer:

N2 has two atoms and atomic number OF Nitrogen is 7. = 14 gm.

...

Calculate the mass of 0.5 mole of N2 gas (mass from mole of molecule).

Answer 2

R.M.M of N2 gas=2* 14  => 28 g mol-1

Hence, 1 mol of N2 gas has mass of 28 g.

so, 0.5 mol will have mass of 28/2 =>14 g
