Answer 1

search it in google you will get correct answer

Answer 2

Explanation:

Molar mass of NItrogen =14g/mole

i.e mass of 1 mole of N=14g

1 mole contains 6.022×10

23

atoms

∴ mass of 6.022×10

23

atoms of N=14g

Mass of 1 atom of N=

6.022×10

23

atoms

14g

Mass of 1 atom of N is 2.32×10

−23

g
