Question

How many moles of n2(g) would contain exactly 4.0 moles of nitrogen atoms?

Answer 1

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 2

Answer : The number of moles of
`N_2` 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
`6.022* 10^(23)` number of nitrogen atoms

So, 4 mole of nitrogen atom contains
`4* 6.022* 10^(23)` number of nitrogen atoms

Now we have to calculate the moles of
`N_2` atoms.

As,
`2* 6.022* 10^(23)` number of nitrogen atoms present in 1 mole of
`N_2` atoms

As,
`4* 6.022* 10^(23)` number of nitrogen atoms present in
`(4* 6.022* 10^(23))/(2* 6.022* 10^(23))=2` mole of
`N_2` atoms

Therefore, the moles of
`N_2` atoms contains are, 2 moles
