Chapter 6 – Quantities in Chemical Reactions – Chemistry They can be atoms, formula units (of ionic compounds), or molecules. That information still needs to be specified. Because 1 H 2 molecule contains 2 H atoms, 1 mol of H 2 molecules (6.02 × 10 23 molecules) has 2 mol of H atoms. Using formulas to indicate how many atoms of each element we have in a substance, we can relate the number of moles ...
