units to know for midterm

[Alexa Pham 1D]

I remember that in one of Dr. Lavelle's past lecture (Week 1, I believe), he went over the SI unit prefixes. For example, G (giga), M (mega), p (pico), etc. Do we have to memorize all these prefixes or only a select few? I'm worried that I won't be able to calculate things correctly on the midterm if I don't remember the values of the prefixes.

Dr. Lavelle has a constants and equations sheet that he will give students during the exam; this sheet can be found on his website. On the sheet, there are a few SI unit prefixes listed, so you will not need to memorize those. As for the other prefixes, you will most likely not need to memorize them since Lavelle usually gives all the information needed on the exam. Otherwise, you can ask the proctoring TAs what it means.

Hope this helps!

Like what the moderator said, I don't think you will need to know them as this class is about application, not memorization. However, if you are really curious, there was a great past thread where people showed what acronyms they used to help memorize them. There is a great explanation there on how to utilize them properly.

I think we likely have to know the common ones like nano, pica, micro, milli, centi, kilo but I noticed on the constants sheet that he gives us the oddball ones like eV.

I would remember them just in case (I also remember memorizing them as a mandatory assignment for my past high school)!

Those that are used frequently (like pm, nm, angstrom) are written on constant sheet (on Chemistry website). I recommend you to look that up!

On the constants and equations worksheet from Professor Lavelle's chem14a website, there is something listed as "1 atm = 101.325 kPa"
Could someone please explain what this means?

We haven't gotten to this section of chemistry (pressure) yet, so you do not have to worry about it for the upcoming midterm. An "atm" is a standard atmosphere, a unit of pressure. A kPA is a kilopascal, another unit of pressure.

does anyone know if we just use the equation sheet from his website, or will he email another sheet out? I remember someone telling me that their TA said Lavelle would email one for us to print for this test specifically

[Dane_Beasley_1E]

My TA let us know that we can print out the constants and equations sheet on Professor Lavelle's website for the test. We can also print out the periodic table on his website to use on the test.

Do you guys know what will be allowed on the midterm? Also do we have to memorize the conversions or will that be provided.

The conversions will be provided. I would say you should memorize the electromagnetic spectrum and the prefixes like giga- , mega- etc.
