Title: Will we be expected...
Post by: 8039 on June 08, 2010, 10:26:00 am
1. To do calibration graphs from scratch? I hate these questions with a passion. From what I've seen so far we only need to pinpoint concentration given an already plotted calibration line?

2. Remember the names of all the polyatomic molecules and their charges?

3. Write down states for massive and obscure molecules (that aren't in the booklet)?

4. Remember how to write sulfuric acid among other common things?

5. When do we actually balanced equations? sometimes it asks, sometimes not but the solutions still have them included

1. Yes, I can't see why not.

2. Yes.

3. No. They're usually lenient. But just think about fatty acids: no double bond indicates that they're probably solid, double bonds suggest that they're liquid.

4. Yes.

5. Just do it anyway.

Thanks, just hope it won't be there.

Side question, does anyone know if 1ug mL^-1 is the same as 1ug g^-1?

Isn't mL = g anyways?

So i guess it would be the same.

They're the same if you use water as your solvent. If you don't, then no (if they don't use water, there'll be something on the density of the solvent).

Oh Okay, Thanks for that :)

If you have to convert, remember:
