Moles and Avogadro’s Number

In the world there are some things that are incredibly important and work perfectly, and most people just don’t know about them.

Indoor plumbing is one of them.  Really, water and other stuff flowing through the walls and floors, like magic.  How does that work?  How does the water get pushed into and out of the house?  Same thing with chemistry math.

There are some amazing connections between the volume of a gas (at any temperature and pressure) with the number of atoms (or molecules) that make up that gas, and the mass that gas has.  If your substance is not a gas, the mass and numbers of atoms or molecules is just as connected.

They are all connected with the chemical idea of MOLES.

One mole is equal to 6.02 x 1023 particles

One mole = the molar mass of the substance

One mole (of gas) = 22.4 liters of gas (at STP)

Moles are central to chem; you must learn the math, you will need LOTS of practice.
There are no short cuts in life, just do the work now.
