I can't seem to get this problem right for the life of me!!!?

The following three solutions were combined:
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).

49.1*0.087 + 41.4*0.072 - 10.4*0.027 = 6.97mM
