youre right. we were taught to use dimenstional analysis as opposed to a formula. i'm a bit confused at this point now. 3a. convert mols (CN)2 to mols CF4. I'm not sure how to set it up. Do i put the mols of (CN)2 I found (which is 2.67 by my caluculations) over 2CF4? ...
March 2, 2008

Chemistry
When you say in step 2a to convert you mols by using grams/molar mass, you do mean to just put 80/the molar mass of (CN)2 correct? because i have been taught to do it differently.

how would you make a 4% percent paraformaldehyde solution? Work: starting from 20% (diluted with PBS) V1C1=V2C2 (100)(20)=(x)(4) x=500 so add 496 ml of PBS (accounting for 4% paraformaldehyde) or would you add 500ml of PBS Thank you
