    What volume does 1 mole of gas occupy at 1 atm pressure and 273.15K?

    PV = nRT so V =nRT/P

    V = (1)(8.314)(273.15)/1

    Im getting 2270.96, the answer is ment to be 22.4L, what am i doing wrong?

    P= 1
    V= ?
    n= 1
    R= 8314
    T= 273.15K

    You need to use a consistent set of units. Atm and L are not SI units. The SI units for pressure are Pascals (Pa), and for volume m^3. Look these up.
