Question

the number of atom in 1.4 gram Nitrogen gas is:​

Answer 1

Answer:

First we will see whether nitrgen is monatomic diatomic

Nitrogen is diatomic

No of atoms=2

Atomic mass = 2×14=28

We know,

No of moles = given mass/molecular mass

N=1.4/28=0.05

No of atoms= n× 6.022×10^23

n=0.05×6.022×10^23= 3.011 ×10^22

Answer 2

14 electron ans is correct
