    I'll do it in english units
    16 is the mol weight
    Ideal gas laws.. pv=nRT or v=nRT/p
    v=solve for

    n=1
    p=23 x 14.696 = 337.87
    R=10.73 ft3 psi/degR lb-mole
    T=459.67 + (1.8 x 55)= 554degR
    so v= 1x10.73x554/(337.87)=17.59
    so density is 16/17.59 = 0.909 lbs/ft3
    do the math to change units in CGS system
