## Homework Statement

Object A and object B are two identical microscopic objects. The table below shows the number of ways to arrange energy in one of these objects, as a function of the amount of energy in the object.

E (joules) 4e-21 6e-21 8e-21 1e-20 1.2e-20 1.4e-20 1.6e-20

# ways 6 20 37 60 90 122 148

When there are 6e-21 joules of energy in object A, what is the entropy of this object?

SA = ? J/K

When there are 1e-20 joules of energy in object B, what is the entropy of this object?

SB = ? J/K

Now the two objects are placed in contact with each other. At this moment, before there is time for any energy flow between the objects, what is the entropy of the combined system of objects A and B?

SAB = ? J/K

## Homework Equations

omega = (q+N-1)!/q!(N-1)!

S = kln(omega)

## The Attempt at a Solution

I don't know how to get the quanta from the energy given...if that's how you do it? When i know the quanta i can find omega and and plug it into the entropy equation.
