Whats the volume of one mole of an ideal gas at standard temperature and pressure

The volume of one mole of an ideal gas at STP = 22.4 L

The ideal gas equation can be written  

where  

P = pressure, atm  

V = volume, liter  

n = number of moles  

R = gas constant = 0.08206 L.atm / mol K  

T = temperature, Kelvin  

n=1 mol

standard temperature and pressure = T = 273 K, P = 1 atm

The volume :

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
