Labeling x-axis on x.y scatter

I've got two columns of information plotted against one another in an x,y scatter. I need the x-axis to reflect each of the 42 numbers I've added in the column and not a preset or fixed range of numbers. (I need to see the actual number that I assigned each x-plot point on the x-axis and not on the plot point itself).

Thanks!!!

Can you upload your excel template here please?

I'm not sure that worked so I'll reply to my post if it fails to attach. OCHEM332L_Spring2014_Lidocaine Data.xlsx

What I need is the column labeled 'molarity' (column J), to have each of the values on the x-axis. So the first number on the x-axis should be 0.527 followed by 0.533 followed by 0.538, etc.

Thanks!
