Calculate the % error. Compare the result with the average molarity of acetic vinegar as determined by previous students.
.8488 Molarity of acetic acid in my experiment
.8701 Molarity of previous students
Is my result of -2.448% correct? Is my sigfigs correct? Is it supposed to be negative?
Homework Answers
yes Your answer is right
(0.8488 x 100 / 0.8701) -100 = 2.44799
But negative sign no need.

Calculate the moles of acetic acid, molarity of the vinegar solution, and mass %. of acetic acid in the vinegar using the average of three good trials used to titrate 5.00 mL of the vinegar. You may assume that the density of your vinegar sample is 1.01 g mL^-1. Drain off unused NaOH solution into a clean container and place it into a designated container. Wash the buret two times with regular tap water, then rinse with deionized water, and...

I am supposed to find the individual and average weight percents of acetic acid in vinegar and the relative percent error between my average results and the manufacturers listed value. Data 6ml vinegar @ 5% acetic acid 3.585g vinegar 42.2ml of NaOH @ 0.100M I'm not sure how to do this at all and want to understand. I know we need to use the molarity equation somewhere.
