In chemical formulas, numbers indicate the quantity (how many) of atoms and molecules there are present. Looking at the formula below, which numbers tell you the amount of molecules present? How many hydrogen atoms are there?
The small number written to the right of an element (letter) tells you how many atoms of that element are present, while the large number to the left of the chemical formula tells you the amount of molecules there are.
For this example there are eight glucose molecules, and twelve hydrogen atoms.
