Consider the titration of a solution of TtRd with the titrant TrNt which proceeds according to the following analytical reaction:

2TrNt + 3TtRd 5PrOd + 2H2O

The equation describing the quantitative relationship between the weight (mass) of TtRd and the concentration of TrNt which applies at the equivalence point of this titration has the following form:

MTrNt x VTrNt = (WtTtRd / Molar MassTtRd) x Stoichiometric Ratio

What is the numerical value of the Stoichiometric Ratio? Express your answer to four significant figures.
NOTE: Since stoichiometric coefficients have unlimited precision, so will the stoichiometric ratio. You are being asked to use four significant figures only out of convenience. Also, give some careful thought on your own to the units which the stoichiometric ratio should have.

While I was washing the dishes the other day, I didn't realize i was stepping on an extension cord while doing it (was barefoot). I experienced a weird tingling sensation at my fingers while washing for a few seconds and it went away as soon as i realized my foot was on the cord and stepped off it. I felt fine afterwards. Is this type of shock a serious one? Also, is it one of those shocks that traveled all the way up my leg and to my fingers? Could it have crossed through my abdomen?

Im trying to solve for L in terms of S but I can't seem to figure out the algebra needed to solve for L when L ^.68 = S^(-.16). Anyone know how to solve for L?
