Here is my data:
Mass of flask ----- 77.649 g
Mass of flask + vinegar ----- 80.903 g
Mass of vinegar ----- 3.254 g
Buret reading of NaOH, initial ----- 49.89 mL
Buret reading of NaOH, final ----- 19.78 mL
Volume of NaOH used ----- 18.22 mL
That is my data. What I need to calculate is the following:
Molar concentration of NaOH
Moles of NaOH added
Moles of CH3COOH in vinegar (%)
Mass of CH3COOH in vinegar
Percent by mass of CH3COOH
I have been looking through all of my notes and trying over and over again to get the answer, but I cannot seem to do it correctly. Please help me!
BTW: I am not just looking for someone to do my work for me. . .I have to repeat this work for 3 more trials from my experiment.
THANK YOU!
