Wouldn't it be 1 sf? They said "10mL ethanol" where that is clearly 1 sf.
I got that too. I got 1.397 first (not sure if it exactly was this) and found i didn't recalculate the concentration, and changed it to 2.397.
Do you do Industrial Chem?
no. did this very unpopular piece of crap chemistry of art.
Yes. Please try and keep it civil with other people, even if you did misread.

Chemistry of Art is the shit man. Half of it is astrophysics.
Add ethanol to allow the aspirin to fully dissolve.
I wrote to aid the blending of the aspirin and water or something like that o_o I read earlier in this thread that we had to discard the first/rough titre? Is this true? I didn't... I though it wasn't that different from the other two results so i used all 3 and got 0.1mol/L NaOH
My final ans was like 300mg or something like that.
You don't need to remove the first one because in the exam, they only gave 3 - normally they give 4 and ask to titrate using 3.I wrote to aid the blending of the aspirin and water or something like that o_o I read earlier in this thread that we had to discard the first/rough titre?

Ahh sweet
yeah using 2 titres seems a bit too little. I also made a typo in my post lolol i was meant to say "i didn't think the rough titre was that different from the other two titres".
Yeah, normally, 2=shit reliability.Ahh sweet
did u ever use that 10mls in ur calculations? if no its not 1 sf
Agreed.
yeah it was dispersion because they were the same series.
