Lesson 16: STP
STP: Standard Temperature & Pressure
- At a specific pressure and temperature, one mole of any gas occupies the same volume.
- At 0 degrees Celsius and 101.3 kPa -> 1 mol = 22.41
- This temperature and pressure is called STP
- 22.4 L/mol is the molar volume at STP
How many litres will 2.3 mol of O2 occupy at STP?
(2.3 mol) (22.4 L/1 mol) = 51.52 = 52 L
Loureal's Awesome Gas Company is found to occupy 12.1 L at STP.
How many moles of gas are there?
(12.1 L) (1 mol/22.4 L) = 0.54 mol
22.4 L/mol such a magical number <3
