Unformatted text preview: depend on the type of gas 2. The vo lume occupied by the mo lecules is not the same in the three samples of gas. 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) 0 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...
