Question

What volume of nitrous oxide (N₂O) at STP will contain 1x10^​24 nitrogen atoms?

Answer 1

At STP,

Volume of 1 mole of N₂O is 22.4L

And ,
In N₂O has 12.044 $\times$10​²³(2N_A) nitrogen atoms are present in 1 mole.
10²⁴ nitrogen atoms are present in $$\begin{gathered} \frac{1}{12.044\times {10}^{23}}\times {10}^{24} \\ =0.8moles \end{gathered}$$


Volume of 1 mole = 22.4 L
Volume of 0.8 mole = 17.92L
