Chemistry
Hi again, I have a question. Why did you divide by 1000? 
Chemistry
Oh okay, thanks again! 
Chemistry
Thank you so much that make so much, but one last question. I see that you are using CH3COOH for the acetic acid instead of HCH3COO. Which one do I use because I'm a little confused 
Chemistry
Il rewrite the last part in case it wasn't clear 1.05mol acid/1L > ?/L ?/L > Lacid/Lsolid 1.05 mol > mass> volume 
Chemistry
When I did the equation I got 0.0583 as the percentage and I am sure I did it wrong. This is what I did... First I calculated the molar mass of HCH3COO = 60.06g/mol Then I found the moles by C X V = 1.02mol/l (0.01L) = 0.0102mol mass of acetic acid> n x M = 0.0102 (60.06... 
Chemistry
Sir, I think you are getting the percentage weight/volume and the volume/volume mixed up. As far as I know shouldn't it be set up more like this.. v/v % = volume of acetic acid divided by volume of vinegar × 100 And the density is 1.05g/mL 
Chemistry
Oh, I was confused on where you got the 60g from. Did you find the molar mass of vinegar and multiply it by the number of moles to get around 60.07g .....60g. Also the question gave the density of the acetic acid 1.05g/mL, am I suppose to incorporate that with anything? 
Chemistry
Sorry for not stating the question clearly, this was a lab report. The lab was finding the concentration of vinegar. Maybe this will give you more of the idea what it is about. This was the trial data we did: Trail 1 Trail 2 Trail 3 Trail 4 Trail 5 Concentration of base(NaOH) ... 
Chemistry
The question is asking the molarity of vinegar, and I am not sure if i did it right. NaOH + HCH3COO = CH3COONa + H2O NaOH C= 0.70mol/L V= 14.6mL > 0.0146L n, NaOH = CxV = 0.70 (0.0146) = 0.01022mol 1 mol NaOH = 0.01022mol NaOH   1...
