Question

Calculate the number of atoms in 1 gram of nitrogen?

Answer 1

Answer:

Nitrogen is found in nature in the form N2, so

Nitrogen is diatomic,

No. Of atoms = 2

Atomic mass = 2×14=28

No. Of moles= 1.4/28=1/2=0.5

Multiply by avagadro number

N=0.5×6.022×10^23

N=3.011×10^22

Answer 2

Answer:

14 gram have 6.023×10²³ so

1gram have 6.023×10²³/14

.430×10²³
