Moles to Volume Conversion (Brian)

-At a specific pressure and temperature one mole of any gas occupies the same volume
-At 0 Celsius and 101.3 Kilo pascals = 22.4 liters
-This temperature and pressure is called STP
-22.4 L/mol is the molar volume at STP

Example:
A certain gas is found to occupy 11.6L at STP. How many moles of gas are there?
11.6L x 1mol = .518 mol
              22.4L

Avogadro's Number (Brian)

-Atoms and molecules are extremely small
-Macroscopic objects contain to many to count or weigh individually
-Amedo Avogadro proposed that the number of atoms in 12.00000g
 of Carbon are equal to a constant (equal to 1 mol of Carbon)
-This value is now called Avogadro's number and forms the basis
 of all quantitative chem

* 1 mol of meters would cross the entire galaxy over 3000 times(1 mol repersents a huge number of   particles)
