A container with 3.1 moles will hold how many liters of gas at STP?
1 Answer
We're asked to find the volume occupied by
To solve this, we can use the idealgas equation:
where

#P# is the pressure of the gas in atmospheres (#"atm"# ) 
#V# is the volume occupied by the gas in liters (#"L"# ) 
#n# is the number of moles of the gas present (#"mol"# ) 
#R# is a constant called the universal gas constant, equal to#0.08206("L"·"atm")/("mol"·"K")# , and 
#T# is the absolute temperature of the system (absolute temperature simply means its Kelvin temperature,#"K"# )
At standard temperature and pressure, the pressure is
Let's now plug in all our known variables, and rearrange the idealgas equation to solve for the volume,
