Asked by Jim_R
hey guys im stumped and burning out. Its mid term time. I got 5 midterms and lab test.
i think im making this more complex than needed
what is 10mg/dL Ca in mEq/L
can u show me a simple way using the valence ? My answer doesnt make sense.
----------------------------
N=(gram solute/mw)/L
(20mg/40.078)dL--->
=0.499 /dL
converts to 5.0 mEq/L
----------------------
is there a simpler way by using the normality and valence ?

I don't know that it's any simpler. You have used essentially the same thing. I usually do it in steps.
N = number milliequivalents/mL = me/mL and
me = molecular weight/valence
40/2 = 20 = eq wt or 0.02 for meq wt.
10 mg/dl = 0.01 g/0.1L = 0.1 g/L
0.1g/20 = 0.005 eq/L = 5 me/L.
