Strategy:
 Avogadro's Law implies that at constant  and , the number of molecules is directly proportional to volume. To find the ratio of atoms, we simply multiply the number of molecules (which is equal for all) by the atomicity (atoms per molecule) of each gas.

Step 1: Determine atomicity for each gas
-  : 1 S  2 O  atoms
-  : 1 S  3 O  atoms
-  : Monoatomic  atom
-  : 1 C  4 H  atoms

Step 2: Build the atom ratio
Since the number of moles (and thus molecules) is the same in each flask, the
