#3# carbon atoms per molecule

Explanation:

The chemical formula for propane is #C_3H_8#
so there are
#color(white)("XX")3# carbon atoms and
#color(white)("XX")8# hydrogen atoms
per molecule

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If you are interested in the structure of propane:
#color(white)("XX")H_3C CH_2 CH_3#
is probably a more exact representation
(but it still simplifies to a Carbon to Hydrogen molecular ratio of #3:8#)
