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 SCNÐ in trial 1 is? ____M

I can't make head or tails out of the post. You might try a vertical listing since spacing is a problem with the board (it ignores all spaces after the first).
