    Use the ideal gas equation

    PV = nRT

    P = 1.00 atm (standard pressure)

    V = ? L

    n = moles = 1.00 mol

    R = gas constant = 0.082057 L atm mol^-1 K^-1

    T = temperature in Kelvin = 273.15 K (standard temperature)

    solve for V

    V = nRT / P

    = 1.00 mol x 0.082057 Latmmol^-1K^-1 x 273.15 K / 1.00 atm

    = 22.4 L

    Vm = V/n = 22,4 L/mol

    V = 22,4 L at STP

    (or V = 24,5 L atSTP).
