I understand how you obtained the grams of acetic acid but how do you find the percent, I am so of acetic acid in vinegar?
The last question on my assignment is to find the % of acetic acid in the vinegar. But their was another previous lab that we did do determine the molarity of NaOH which was .0307. So I started from the point where I took 10 mLs of diluted solution and 2
Disregard this question I figured it out, THanks for all the help Bob
Disregard this thread I found the answer
In my math I took 8g of AgNo3/1.69.8731 g/mol=.0471 mol of AgNo3 Then since there is only one AgNO3 and one AgCL, then AgCl's has a mol of .0471, multiply that by its molecular weight of 143.321 and I receive 6.75 grams. not 3.4, where did I did I do
excuse me the product was AgCl not NaCl, that probably does not change the step but thought I would correct myself.
