The Sackur-Tetrode Equation calculator calculates the entropy of an ideal gas for distinguishable and indistinguishable molecules.
(V) Volume of gas (in $m^{3}$): (N) Number of particles of gas: (Note: for 6.022x$10^{23}$, you should write 6.022e+23) (m) Mass of gas (in kg): (U) Internal energy of gas (in joule):
(V) Volume of gas (in $m^{3}$): (N) Number of particles of gas: (Note: for 6.022x$10^{23}$, you should write 6.022e+23) (m) Mass of gas (in kg): (U) Internal energy of gas (in joule):
