Homework Help: chemistry

Posted by Jim_R on Sunday, February 7, 2010 at 2:12am.

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 ?
