The calculated value of 26.5 g/L is now used as a factor to determine the
volume of solution that can be prepared. However, the reciprocal of the value must be
used as a factor. If there are 26.5 grams per liter then for every liter there are 26.5
grams of solute. This relationship is true of all factors we have used.

Section III. MILLIEQUIVALENT PER LITER (mEq/L) SOLUTIONS
4-7.
INTRODUCTION
Milliequivalent per liter problems are based on the same principle as normality. If
we examine the definition of normality, we will find that a normal solution contains one
gram equivalent weight per liter of solution. Equivalently, we can say that a normal
solution is one equivalent per liter of solution (Eq/L). A milliequivalent per liter solution
would, therefore, contain one milliequivalent weight per liter of solution.
4-8.
DISCUSSION
a. A milliequivalent = 0.001 equivalent and 1 equivalent = 1000 milliequivalents.
b. A milliequivalent has the numerical value of one equivalent weight expressed
in mg/mEq.
c. To convert Eq/L to mEq/L and vice versa multiply the concentration by the
conversion factor 1000 mEq/1 Eq as appropriate.
