👉 "Decimole" is a term used in chemistry to describe a substance that has 10,000 times as many atoms as one mole of that substance. This can be understood by understanding how the atomic number and mass number of an element determine its chemical properties and how much mass (or weight) each atom carries with it. The formula for calculating the number of atoms in a compound is: \[ \text{Number of Atoms} = \frac{\text{Mass of
