one mole of any gas at STP has a volume of __._ Liters.
22.4
22.4 Liters is often called the _____ ______.
Molar Volume
ex. 3.4 moles of O2 occupies how much volume?
76 Liters O2
Gas occupies 240 L. How many moles of the gas are there?
240 L gas
--------------
22.4 liters per mole = 11 moles
how many grams of carbon monoxide are in 26.8 L of carbon monoxide at STP?
33.5 grams CO
Liters CO => moles CO => grams CO
divide 26.8 by 22.4 then take 1.19 and multiply it by the molar mass of CO
How many liters of methane (CH4 are in 3.35x10^32 molecules of methane at STP?
1.25x10^10 liters CH4
Molecules => moles => Liters
3.35x10^32 divided by 6.02X10^23 and multiply that number by 22.4 liters
