STP corresponds to 273 K (0° Celsius) and 1 atm

so PV = nRT

remember R us the gas constant: 0.0821 liter·atm/mol·K

1(atm)(V) = (1mol)(0.0821 liter·atm/mol·K )(273 K)

V = 22.4133 Liters

you need to round volume to 3 significant figures

V = 22.4 L

Next time put this in the chemistry section :P

22.4 L

To solve, plug in the appropriate values into the ideal gas law, PV=nRT.

This is the volume of one mole of ANY gas at STP, due to Avogadro's Law.
