so we did a chem lab and one of the questions is to tabulate the amount of S2O3 consumed in moles and times (sec) for each run.

I'm just not sure how to calculate the amount consumed. Can someone please explain how?

I assume you have a sequence of measurements of mols/grams/amount vs time in seconds.
amount at start - amount at 1 sec = amount consumed. This answer is general I know but so is your question with no data.
oh okay, that makes sense & a little obvious haha . Thanks.
