I don't know if I have all the necessary data because I was sick and left hafway through lab and my lab partner wouldn't give me the necessary info so I only have what I started off with. am I missing anything from the expirement that would be required for me to calculate?


Molarity of NaOH = 0.1987
Volume of vinegar used = 5mL
NaOH, start = 50mL
naOH buret, finish = 23.5
Density of 5% Vinegar solution =

Volume of NaOH used =
Moles of NaOH added =
Moles of Acetic Acid in sample =
Molarity of vinegar =
Mean vlaue for vinegar molarity: =
Mass (g) of acetic acid per liter in vinegar =
Mass (g) of solution per liter of vinegar =
Weight percent of acetic acid =

, I hate it when people don't compromise. Yea you are missing vital info. try to get it from someone else.

Oh damn Thanks for letting me know but my professor said tonight was the deadline for emailing it.

Only part you are missing is this:

Density of 5% Vinegar solution =

Rest you can calculate.

Either use google to estimate; or just the density of water. It is a fairly dil. solution. You should be fine.

Can someone  calculate them for me? I haven't figured out how to do it yet and I want to turn it in as soon as possible (if my professor'll even take it at this point) I'm learning how to do them now but I want to send it as soon as I can.

No, we don't do homework for others.

See if this page helps:

You will also need to convert molarity to percentage. See explanation of how to do the opposite conversion: http://www.chembuddy.com/?left=concentration&right=percentage-to-molarity

cool story. thanks for the links

When asking for weight percent of acetic acid, is that the same thing as asking for Mass percent? And another dumb question... is "molarity of vinegar" the same as "molarity of acetic acid in vinegar sample"?

Yes & yes.
