How many of you are having trouble figuring out PS3.1, 3.2 and 3.3 on our Problem Set? Yea, I know these three questions are confusing..what is dr. g. talking about in these three questions? Try reviewing this 2 minute 38 second clip from Friday, September 8, 2000 lecture and see if these probems are a little clearer.
Need some help doing PS3.4? Check out this 1 minute and 30 second clip from Friday, September 8, 2000 lecture and see if it helps.
Here is a 5 minute clip from Friday, September 8, 2000 lecture which covers some of the calculations required in PS3.5.
An observant student, Justin Battista, has found another typo/error in PS3. PS3.6a the percentage of carbon and oxygen are reversed. The problem should read...
Determine the empirical formula for vitamin C which is 40.9 % carbon, 54.5 % oxygen and 4.60% hydrogen.
A typo has been discovered in PS3.10d change sodium in 'sodium nitrate' to potassium nitrate and you will be able to do that problem correctly.
Tables 2.3 (p 67), 2.4 (p 69), 2.5 (p 69) and 2.7 (p 73). I'll give you some tricks to make Tables 2.3 and 2.4 real easy to remember, but Table 2.5 and 2.7 have to be memorized. I promise the first exam will have some nomenclature questions.
