I can not figure this out I have been working on it forever, why is it soooo difficult or am I doing it wrong?!?!?
The following aqueous solutions are mixed together:
1. 49.1 mL of 0.087 M hydrochloric acid.

2. 41.4 mL of 0.072 M nitric acid.

3. 10.4 mL of 0.027 M sodium hydroxide.

What is the concentration of H+ in the mixture? Express your answer in mM (1000 mM = 1 M).

First I know I need to find the product and balance the equation.. right?  This is the part I can not figure out... I know HCL+NHO3+NaOH -> H2O .. because it is a redox reaction....?  
Then I find out how many H+ are in each solution
HCL (.0491L)(.087m/L)= 4.27 *10-3 mole of H+, and I will do this for each one, then I will find the limiting reactant, the one with the least moles of H+.  I feel like Im not doing this right Im soooooo confused I have been working on this for hours please someone!
