Answer:

120

Explanation:

One molecule of glucose has 6 atoms, as you can see in carbon's index.( #C_6#).
In 20 molecules there will be #6*20# carbon atoms.
It can also be written down as:
20 #C_6H_12O_6#
So, written down like this there are #20*6# carbon molecules, #12*20# hydrogen atoms and #6*20# oxygen molecules.
