<pre wrap="">Dr.Pounds,
The graph that we should bring tomorrow only includes the standards right?
In the procedure it says that the concentration of [FeSCN2+] is equal to the initial [SCN-], what values do we use??
Thankyou

Yes -- you only have a graph for your standards. You may include
your blank as one of your standards.<br>

Use the <img style="vertical-align: middle"

alt="$M_1V_1=M_2V_2$"> equation again. I believe that you used
1, 3, and 5 ml of the KSCN. Therfore use that information, the
concentration of the KSCN you got out of the fume hood, and the
final volume for each sample to come up with the concentration.<br>
