Respuesta :

each nitrogen molecule had 2 Nitrogen atoms.
So 2 moles of nitrogen gas molecules will have 4 moles of nitrogen atoms.Answer is 2moles

Answer : The number of moles of [tex]N_2[/tex] contains are, 2 moles.

Explanation : Given,

Moles of nitrogen atoms = 4 moles

First we have to calculate the number of nitrogen atoms.

As, 1 mole of nitrogen atom contains [tex]6.022\times 10^{23}[/tex] number of nitrogen atoms

So, 4 mole of nitrogen atom contains [tex]4\times 6.022\times 10^{23}[/tex] number of nitrogen atoms

Now we have to calculate the moles of [tex]N_2[/tex] atoms.

As, [tex]2\times 6.022\times 10^{23}[/tex] number of nitrogen atoms present in 1 mole of [tex]N_2[/tex] atoms

As, [tex]4\times 6.022\times 10^{23}[/tex] number of nitrogen atoms present in [tex]\frac{4\times 6.022\times 10^{23}}{2\times 6.022\times 10^{23}}=2[/tex] mole of [tex]N_2[/tex] atoms

Therefore, the moles of [tex]N_2[/tex] atoms contains are, 2 moles
