It is in chemical sense an organic molecule. Glyphosate can only be originated by organic synthesis by the human. Otherwise, glyphosate is not present in nature.
How many H atoms are present in a chemical formula?
By looking at an actual chemical formula for a compound, we could tell you how many hydrogen atoms there are per molecule (or at least per formula unit) of that compound.Without the specific chemical formula, we can't. So the question is meaningless ... how many hydrogen atoms are present in a chemical formula depends on what the chemical formula is.
In a chemical formula what do subscripts mean?
In a chemical formula, the significance of subscripts is that it tells you how many atoms of a certain element are present in a structure.
