The Sackur-Tetrode Equation gives the entropy of a sample of n moles of monatomic ideal gas as a function of its internal energy U and volume V S(U, V) = 5/2 n R + n R In (V/n N_A(4piM U/3nN^2_Ah^2)^3/2) In the equation, R is the gas constant, M is the molar mass, N_4 is Avogadro's number, and h is Plank's constant. The equation can be derived using S = k ln W and directly computing W, the number of...

For the gas constant, use R = 8.314 J/mol-K For Avogadro's number, use N_0 = 6.022 times 10^23 molecules. Be careful of units! All the conversions you need are in the information section of the lab. Suppose the volume of the syringe is 47.5 cc. You measure the pressure as 1.58 atm, and the temperature as 19.8 degree C. Assume: the diameter of the plunger on the syringe is 1.44 cm. Find the number of moles of gas in the...
