Re: Calculating Degeneracy
The equation W=2^n only refers to a specific model where the model is only in two microstates. In order to find the degeneracy of any molecule/atom the equation used is W=M^n where M= the number of states and n= number of molecules/atoms

Question 9.29
List the following substances in order of increasing molar entropy at 298 K: H2O(l), H2O(g), H2O(s), C(s,diamond).
How am i supposed to figure out the molar entropy?
Would i use the equation with the boltzman constant or the Change of entropy equation?

Re: Question on Chapter 3, Question 19? [ENDORSED]
3.19 part e) First take into consideration the actual electron configuration of Ni. When finding out the configuration take into account that the d subshell acts as a lower charge so should be in front of the configuration. So naturally, Ni configuration is [Ar]3d84s2 it is 3d8 because if you count ...

Re: Rydberg Constant [ENDORSED]
The Rydberg constant as you have seen on google differs from the constant as seen in the course reader only by the units they are given. In reality, all values of the rydberg constant are equal such as 3.29* 10^15 Hz = 10973731.6 m-1 Because the units have changed, you have to also change the number...

Re: Workbook Self Test pg. 11 #8
First off, the problem asks for moles of CO2 and not the grams of both formulas. So, we first look at the question, moles are the one needed to be found, to be exact, moles of CO2. In order to find the number of CO2 moles needed, Dimensional Analysis would be the method we use to convert from grams ...
