A gas occupies 3.0L of space at 1.5 atm and 20◦C, if the pressure is increased to 2.5 atm and the temperature rises to 30◦C , how much space will the gas occupy? Avogadro’s Hypothesis Equal volume of gases at the same T and P have the same number of molecules V ___________ α Formula: V and n are directly proportional. They increase together and they decrease together. WHY? ______ and ____ are constant Suppose we have a 12.2 L sample containing 0.50 moles of oxygen gas, O2 . If all of this O2 is converted to ozone, O3 what is the new volume of the gas? 3O2 (g) 2O3 (g) Ideal Gas Law An gas is a ___________________________________ gas that exactly obeys the ideal gas law _________________________ gases are ideal, but treating them ideal allows us to do calculations Ideal Gas Law: R is the ____________________________________________________ R= How much space does 1 mole of oxygen gas occupy at STP?
