Question

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

Answer 1

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 \(\sf 2:3:4\)
