Don't mean to double post but I can't edit my message... I have some further questions that I'm interested in answering here.
From the results of question 1, calculate the average value for the number of moles of vitamin C titrated.
Report the final value to the appropriate number of significant figures.
-- To answer this I would just take the mole value above (for trial 1); do the same thing for trial do, add them together and divide by 2--correct?
3. Calculate the % error of the mole values used to calculate the average in question 2.
Not sure how I do this.
Using the average moles of vitamin C titrated, calculate the amount of vitamin C, in mg, that was in the
tablet you analyzed. (Hint: Remember how the tablet was prepared and put into solution before titration).
I believe for this I can write:
Avg moles vitamin C * XXXX grams vitamin C / 1 mole vitamin C * 1000mg/1g * 20 (this is a value given to us)
is that correct technique?
Calculate the % composition of vitamin C in the tablet.
Not sure how to do this..
