<p>Dr. Pounds,</p>
<p>Can you let me know which formulas and constants will be
provided on the exam and which wont be? I have the ones we use
a lot for sapling memorized, such as: PV=nRT, but I still want
to make sure I have everything I need to know memorized. </p>
</div>
</blockquote>
<br>
I just e-mail the class a sample cover page with the formulas that
you can expect on every exam. I expect you to know the gas
constant for R in the units we discussed in class as well as how to
convert between celcius and kelvin.<br>

<p>Can I also know the format of the exam? </p>

<br>
The exam will be approximately half multiple choice and half worked
out numerical problems. <br>

<p>The exam will only consist of ch 18, 10, 11, and 13 correct?</p>
</div>
</blockquote>
<br>
Yes, the first 5 sections of chapter 18 and then the sections
mentioned in the syllabus for chapters 10, 11, and 13. <br>

<p>On Chapter 10 Burdge, number 72, how do you know that the
mole fraction gives the volume fraction?</p>
</div>
</blockquote>
Avogadro's hypothesis -- "equal volumes of gas contain equal number
of gas molecules". We can also state that as "equal volumes of gas
contain equal moles of molecules". Because of this we can use mole
fraction and volume fraction interchangeably for gases. <br>
<br>
Let me know if you need more clarification.<br>

<p>Thanks!</p>
