Avogadro's Number Of Particles
Matter can be quantified in three different ways. The first way is to count how many of something you have, For example, you can count the number of shirts in your closet. The second way to quantify or measure matter is to determine its mass. For example, you can buy bananas by the pound. The third and last way to quantify or measure matter is to determine its volume. For example, people by gasoline by the gallon. Chemists use a unit that is a certain number of particles. This unit is known as the mole. A mole is the quantity of anything that has the same number of particles found in 12.000 grams of carbon-12. That number of particles is Avogadro's Number which is about 6.02 x 1023 , representative particles. That is an SI unit for measuring the

Representative particles refer to the species present in a substance which are usually atoms and molecules. Representative particles of most elements is the atom. Iron is composed of iron atoms.
There is a conversion factor that can convert from a mole of a substance to the mass of that substance. The first step is to calculate the molar mass of an element or compound. Molar mass is a physical property defined as the mass of a given substance divided by the amount of substance. Molar Mass is expressed as g/mol. For example, if you had two carbon atoms, you would multiply the atomic mass by two. You need to use the molar mass to convert between the mass of a substance and the moles of a substance. The conversion factor depends on the relationship: one molar mass equals one mole. If you were given 3 moles of NaCl, the molar mass would be 58.5 grams per mole of
