there was an error in a value that they reported to me this

What is imperative, however, is that in your report for you put
the DILUTED concentrations (what the concentrations are in each
of the flasks).<br>

<p>Hello Dr. Pounds,</p>
<p> </p>
<p>I was talking to my lab partner, and she told me that we
needed the initial concentrations (that we written on the
jugs for the KI and the Na2S2O3). All I have written is what
was listed in the lab, but I do not have what was on the
jugs. The only one I have from the lab is the concentration
for H2O2. What should we do?</p>
