Answer #1

The residual entropy is given by the equation,S=Kb lnW where Kb is Boltzman constant,W is the number of possible orientation of the molecule.here,the given molecule is hexagonal and the number of possible orientation will be 6.Thus,

W will be 6 to the powe of N

S=Kb x ln 6 tothe power of N,where N is avogadro number(there will be avogadro no. of molecules in one mole)

ie,S=Kbx N ln6

=R ln 6 because KbxN is R,the universal gas constant.

=8.314J/k x 1.7917=14.894J/K mol

Metallic magnesium has a hexagonal close-packed structure and density of 1.74g/cm^3. Assume magnesium atoms to be spheres of radius r. Because magnesium has a close-packed structure, 74.1% of the space is occupied by atoms. Calculate the volume of each atom; then find the atomic radius r. the volume of a sphere is equal to 4π^3/3.

A pure gaseous hydrocarbon has a density of 0.103 lb/cu ft at 14.7 psia and 100 degrees F. Chemical analysis shows that there are two hydrogen atoms for each carbon atom in each molecule. What is the formula of this molecule? Assume that the hydrocarbon acts like an ideal gas. Additional instruction from teacher : calculate the molecular weight of the molecule. Then divide it by the molecular weight of CH2 , which is the simplest molecule that has two...

HCl has a bond force constant of 480 N/m, oscillates at 8.66x10^13 Hz and an equilibrium bond length of 0.127nm. (a) At what wavelength (in μm) and wavenumber (in cm−1) would you expect such a molecule to absorb light? (b) When the molecule is in its ground energy state, the two atoms do not simply rest at a fixed distance of 0.127 nm and, instead, they are constantly in motion. What is the maximum and minimum distance of separation between...

Suppose that 4.8 moles of an ideal diatomic gas has a temperature of 1061 K, and that each molecule has a mass 2.32 × 10-26 kg and can move in three dimensions, rotate in two dimensions, and vibrate in one dimension as the bond between the atoms stretches and compresses. It may help you to recall that the number of gas molecules is equal to Avagadros number (6.022 × 1023) times the number of moles of the gas. a) How...

It is well known that similarity in attitudes, beliefs, and interests play an important role in interpersonal attraction. Thus, correlations for attitudes between married couples should be strong. Suppose a social psychologist developed a questionnaire that measures how liberal or conservative one’s attitudes are. Low scores indicate that the person has liberal attitudes, whereas high scores indicate conservatism. The following data were obtained from married couples: Couple Spouse 1 Spouse 2 A 11 15 B 6 4 C 18 20...
