Hi, The equation you have is correct. The mole ratio of acid to base is 1:2 since 1 mol of acid reacts with 2 moles of base.
for c, Molarity is given by: so the number of moles of base are given by:
the ratio of acid to base is so the moles of acid are:
I hope you get the idea of where the equation comes from. Now what you have to do it to put the values: a=1, b=2. Mb is the molarity of sodium hydroxide that you have used in the experiment and Vb is the volume that you have transferred in the flask to complete the titration. For example you used 0.1 M NaOH and the volume consumed was 13.2 mL the number of moles of acid would be:
You need to put your own values from the lab experiment.
Now, you have to divide the moles of acid by the mass of candy
suppose you had a 7 grams candy so
Hope that helps.
