Homework Help: Chemistry.. help plz

Posted by Amy on Sunday, April 13, 2008 at 4:20pm.

The concentration and volume of reagents combined in each trial are listed in the table below:

Trial 00020 M 00020 M H2O(mL)
Fe(NO3)3(mL) KSCN (mL)
1 5 2 3
2 5 3 2
3 5 4 1
4 5 5 0

Initially (right after combining and before any reaction occurs) the concentration of Fe3+ in trial 2 is
____M.

k so so far i have this can someone tell me if this is right...

3 ml Fe(NO)3 x (.0002 moles Fe(NO)3/ 1000ml Fe (NO)3) x (1 mole Fe (III)/ 1 mole Fe (NO)3)= .0000006 mol Fe (III)

then i think we are supposed to divide by total volume but i dnt know if it would be total volume for just trial 2 or the whole chart?
