  1. ***Chemistry - Fall 2005***

    Congratulations! 101.2 That's 4 significant figures or 1.01 x 10(exp2) LOL-----Keep it up!
  2. CNA training

    I think that post was from 2004.
  3. ***Chemistry - Fall 2005***

    Soleilpie- My professor says that they were probably just showing the relation between the units- the answer was exactly the same no matter what the units were. So no conversion was necessary. I found a good website chemistry.about.com/od/gener...
  4. ***Chemistry - Fall 2005***

    mass= g vol = mL the density is equal to g/mL because m/v=d
  5. ***Chemistry - Fall 2005***

    the answer would be in cm3 and the 212.52 you have to change into 2 significant figures so the answer would be 2.1 x 10(exp 2) cm3 or ml ----------i think.
  6. ***Chemistry - Fall 2005***

    1 cm3 is equal to 1 mL is that what you are asking? No conversion math necessary
  7. ***Chemistry - Fall 2005***

    OK- I'm going to give this a try 500mg x 1g/10(-3)mg= 500g x 10 (-3) or .500g .52 L x 10 (-3)mL/1L= .52 x 10 (-3) or 520. mL now .500g/520. mL = 0.000961538 or 9.6 x 10(-4) g/mL As far as the significant figures- When looking at 500 with no decimal a...

    :chuckle that's funny paula. thanks.
  9. ***Chemistry - Fall 2005***

    ooooooooh! Thanks Fun2care. Upon closer examination, I see Moonepie also explained that in her answer. :imbar And this is only chapter 1? I have taken many of my other pre-reqs. and really enjoyed them. I knew this would not be my forte. Pray f...
  10. ***Chemistry - Fall 2005***

    Thanks Moonpie. I now have the answers. This is what they are: The first one is 11.3 kg/m3- I don't understand why it is kg/m3 instead of g/mL - Do you?, The next one was set up just as you had it 1.2/.12 = 10g, The next one came out close to you...

    Thanks Paula- Every bit helps. I'll keep my fingers crossed for you
  12. ***Chemistry - Fall 2005***

    :rotfl: Help! Ok, I have 3 problems I just can not figure out. 1. A sample of lead shot weighing 343.6 g was added to a graduated cylinder partially filled with isopropyl alcohol (enough to immerse the lead completely). As a result, the alcohol l...

    Hi. I'm taking Chemistry w/lab this fall also. I'm already chewing my fingernails. I took Biology this summer, loved it but chemistry looks confusing. It's great to have this forum hopefully we can help each other through.
  14. Help With Cna Training!!!

    Thank you for all your responses. This has been so helpful. I felt a little dumb asking the question "what does a CNA do?" but I'm glad I did. . Most CNA courses in CT seem to be fairly short, I think I can handle taking the course along with my ...
