Beyond what volume of added acid is the ph calculated by focusing on the amount of excess strong acid added?

In an acid base titration (for example a strong acid and strong base like HCl and NaOH), at equivalence point, the number moles of acid is equal to the number of moles of base.

HCl + NaOH NaCl + H2O

Moles of Acid = Moles of Base

V(HCl) * M(HCl) = V(NaOH)*M(NaOH)

Now, beyond the equivalence point as more acid is added, the resulting pH will depend on the excess acid present.

some sources quote the lethal dose, for an average 170lbs opiate-naive individual is between 75 and 375 mg

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
