However, the volume occupied by the mo lecules is negligible compared to the intermo lecular distances (mo lecules of gas are very far apart from each other) 15 Chemistry 101 Chapter 5 AVOGADRO’S LAW
· Equal volumes of different gases at the same temperature and pressure, contain the same number of molecules. Consequences: 1. Equal number of different gaseous mo lecules (equal number of mo les of gas), at the same temperature and pressure, occupy equal vo lumes. 2
2. 1 mo le o f any gas (6.02 x 10 3 gaseous molecules) occupies the same vo lume under the same condit ions of temperature and pressure. o At 0 C and 760.0 torr (1.000 atm), 1 mol of any gas occupies 22.4 L Vm = Molar Gas Volume = 22.4 L 0
0 C(273 K) and 760.0torr(760.0mm Hg, or 1.000 atm) are referred to as: STP (Standard Temperature and Pressure)
Vm = 22.4 L at STP (O C and 760.0 torr) 3. The Volume of a gas is direct ly proportional to the number of gaseous molecules it contains (number of mo les o f gas) V = Volume of gas n = Number of mo les of gas V a n V = a n or directly proportional constant 1...
