So that's why I get the wrong answerby David (no login)
Still it's only about 10% out.
I should have copy and pasted a real program like the one below to calculate the entropy of fluorine gas.
Anyway my original query is why exactly would you need CONSTANT
t = 298.15 'standard temp
h = 6.626E-34 'planck's const
k = 1.3805E-23 'boltzmann's const
na = 6.022E+23 'avagadros' const
pi = 3.141593
u = 1.66054E-27 'atomic mass unit
r = 8.314 ' gas constant
V0 = .0248 'molar volume
c = 2.998E+08 'speed of light
'mass, bond length of F2
m = 19!: bl = 1.4178E-10
lam = h / (SQR(2 * pi * 2 * m * u * k * t))
qt = (V0 / (na * lam * lam * lam))
s2 = r * LOG(qt)
i = m * bl * bl / 2
b = h / (8 * pi * pi * i * u)
sm = 2!
qr = (k * t) / (sm * h * b)
s3 = r * LOG(qr)
PRINT "molar entropy of F2 = "; 3.5 * r + s2 + s3; " J/K"
