four 1 l flasks are separately filled with he o2 o3 and nh3 at same temperature and pressure. find ratio of no.of atom in them

Question

aaronq · Answer

If we assume that they behave as ideal gases, then the number of moles, when T and P are constant, are the same for all three gases. This means that the number of molecules is the same, but they have different numbers of atoms.

$\sf O_2$ has 2 atoms per molecule
$\sf O_3$ has 3
$\sf NH_3$ has 4


So the ratio of $\sf O_2:O_3:NH_3$ is $\sf 2:3:4$
