Well, what is pH? Roughly it's the negative log of the molarity of H

^{+}. The pH of blood is about 7.4, so you can solve7.4 = -log [H

^{+}]and find the concentration of H

^{+}in moles/L.Then you just multiply by the volume to find the moles of H

^{+}.For the deficit part, do you mean in relation to pH 7 or to the OH

^{-}ions? If the former, you follow the same steps as above, but solve for [H^{+}] for pH 7. Then you subtract the pH 7.4 moles from the pH 7 moles to find the deficit.If the latter, you use the equation for pOH:

pOH = 14 - pH = -log [OH

^{-}]Solve for the molarity of OH

^{-}, multiply by the volume, and subtract the pH 7.4 moles from the pOH (14 - 7.4) moles.
